Roland SR-JV80 Techno Collection: The Budget Producer’s Dream in 1997

If you were a budget-conscious electronic music producer back in 1997, your studio setup likely consisted of a Roland JV-1080 and a 16-channel Mackie mixer—because, frankly, that’s all you could afford. In the underground scene, house and techno were the dominant genres, and while the JV-1080 was a powerhouse synth with little real competition, it had a major weakness: drum sounds for electronic music of that era.

The Problem – Weak Drums for House/Techno in the JV-1080
The JV-1080 was an excellent-sounding unit, boasting lush pads, rich leads, and a massive library of usable patches. But when it came to crafting house and techno beats, it fell short. The classic 808 and 909 drum sounds were nowhere to be found, leaving producers with a serious gap in their productions. At the time, a professional sampler could easily set you back $3,000—an unattainable price for most bedroom musicians (over $6k in today’s money).

Heaven Sent for Roland JV owners
Before the Techno card, in 1995 Roland released the SR-JV80 Dance expansion card, which also catered to house and techno producers. However, due to copyright issues, it was pulled from production and became hard to find.

Then in 1997 came the Roland SR-JV80 Techno expansion board, and just like Dance expansion it changed everything for JV-1080 owners. This board was packed with 200 drum sounds exclusively for house and techno, delivering the much-needed 808s and 909s that were essential for club tracks which was dream come true for an average bedroom producer with a JV-1080 back then. For those who couldn’t afford a sampler but desperately needed high-quality drum sounds, this card was heaven-sent just like once was the Dance Expansion. The Techno card effectively took its place, providing an alternative for producers who had missed out on the Dance expansion. If you wanted to release your house/techno music back then, you essentially need to have the 909, 808 flavours in your tracks, you just couldn’t do it with 1080’s Rock and Roll or Jazz drumset as this was considered Passé and people would probably laugh at you if you pulled something like that, although not a bad idea on its own. The alternative was to purchase the 909 but again, these already started climbing up the price. I know, I was there. 🙂

Strengths and Weaknesses
The Techno expansion offered a total of 255 patches, many of which were modern sounding at the time. The bass department left something to be desired. The board attempted to emulate the Roland TB-303’s iconic acid bassline, but the results were overly distorted and not particularly convincing. In fact, they bore a strong resemblance to the bass sounds of the MC-303—decent but far from authentic 303 emulations. This would be my only minor critique.

But where the card truly shined was in its drum sounds! To this day, it remains one of the best-sounding drum expansions Roland ever released for the SR-JV80 series. Compared to other expansion boards, the Techno card’s drum samples had an unmatched punch, making it an essential tool for 90s electronic music production.

The rest of the card contained a nice selection of pad sounds of which many sound excellent, pulsating trance-type sounds, some nice analog poly emulations, a selection of good sounding organ sounds, chord stabs, industrial sounds, and some rave type effects. I couln’t help but notice that a few of the patches are simply modified stock JV-1080 patches. As someone who grew up programming JV-1080 I can recognize them from 100,000 feet. This was the only oddity I encountered with the card. Other than that, and putting it all in the context of the era I would say back then this card was and excellent choice and worth every penny.

Context: How Producers Used the JV-1080 with the Techno Expansion
With the JV-1080 offering only six outputs, producers had to be strategic in their routing. A typical setup might look like this:

  • Main outputs: Pads, strings, leads which benefited from onboard effects.
  • Output 3: Kick drum, isolated for extra low-end headroom.
  • Output 4: Hi-hats, allowing for separate high-frequency processing.
  • Output 5: Claps, snares, and other percussion elements.
  • Output 6: Bass, kept separate for independent processing.

As of main outputs, for example you would route the lead into EFX block to apply a Tempo Delay, while you would route the Pad or String into Chours and Reverb. That way the two sounds would not overlap too much, would use different effects eventually exiting the unit accross the same pair of stereo outputs. Headroom of JV-1080 was ok, but adding more that that would blur out things pretty quick.

By utilizing additional outputs efficiently, producers would expand the total dynamic range of the system and in many cases could achieve a sound that rivaled studios with gear many times as expensive. The Techno expansion effectively leveled the playing field, giving budget musicians the ability to craft professional-grade tracks.

Nostalgia & Retro Appeal
For those who love working with vintage gear or want to recreate the sound of 90s house and techno, the SR-JV80 Techno expansion is a welcoming addition. It’s incredible how much can be squeezed out of a JV-1080 with just 64 voices of polyphony. Careful voice allocation (available in Performance menu), mono modes, and polyphonic limitations were all part of the workflow, but when used right, the results were excellent (speaking in the context of that era).

The Legacy: Minimal Gear, Maximum Output
I personally know members of a band whose album received a 90% rating in Future Music Magazine in 1996—and their entire setup consisted of a Roland JV-1080 with one expansion board, a Mackie mixer, MIDI controller and a JV-880. This proves just how powerful and game-changing these expansion boards were for producers who knew how to work with limitations.

For those looking to recapture the magic of 90s underground electronic music, the SR-JV80 Techno expansion remains a true gem—one that gave budget producers a fighting chance in a world dominated by expensive gear.

SR-JV80 Wi-Fi Expansion Board

A Gearspace forum member, Connor Zheng, came up with this new design for an SR-JV expansion board that can load any image of either an existing or custom-made SR-JV board for Roland rompler synthesizers without the need for cables or additional interfaces. You literally do it using Wi-Fi. A similar product exists from Sector 101; however, this is, in my opinion, a more elegant solution as it does not require and of the cables or the pricy Sector 101 Programmer. Plus it is much cheaper. However, keep in mind with the SR-JV80 Wi-Fi you can not dump your existing SR-JV cards, you need Sector 101’s Programmer.

Roland’s SR-JV80 expansion boards were a game-changer for musicians and producers in the 1990s and early 2000s. Originally designed and programmed for JV-80 synthesizer and later post 1995 versions for Super JV series, these PCM-based expansion boards added a vast range of high-quality sounds, from orchestral ensembles to vintage synths and world instruments.

Each board focused on a specific genre or instrument type. Classics like SR-JV80-04 Vintage Synth delivered iconic analog emulations, while SR-JV80-02 Orchestral provided lush strings and cinematic textures. The SR-JV80-09 Session was a go-to for studio musicians, packed with versatile pianos, basses, and drums.

Though digital synth technology has evolved, these expansion boards remain sought after by collectors and nostalgic producers. Their distinctive character and warm PCM samples still hold up, proving that great sounds never go out of style.

Preparing The Roland JV-80 Synthesizer
I was actually the first to purchase this board, hence I ended up with serial number 0001. To avoid any embarrassing moments, I’ve decided to restore the aging power supply of my JV-80 to ensure all voltages are correct and to extend the lifespan of this uniquely sounding Roland synthesizer. Out with the old:

In with the new:

The battery was near its end of life, so it was replaced as well:

Testing The Board
I have a total of 5 SR-JV80 boards: Pop, World, Super Sound Set, Orchestral and Vintage. While waiting for the board to arrive, I’ve borrowed Sector 101’s card reader from a friend and dumped card’s contents into .BIN files. Kindly: do not ask me for these BIN files—I do not support piracy. If you want to dump your existing SR-JV card, simply borrow Sector 101’s Programmer card reader from someone or ask someone who has one to dump the card for you.

With the binary files available, it was time to insert this new card into my JV-80 and upload the fresh content. Of course, I chose the Vintage Card. Because now I will be having two, I can directly record both the JV-80 and JV-1080 at the same time and compare their sonic differences—of which there will be plenty due to their different filters and effect algorithms. Important thing to keep in mind, all of the pre 1995 SR-JV boards were designed and programmed exclusively for Roland JV-80 synthesizer which is why the only way to properly hear these cards is to have the actual JV-80 synth. On any of the later Super JV series they will sound different, in some situations even unpleasant.

I plan to do sonic difference test in the future as I own JV-80, JV-1080 and JD-990. Ideally, I would have a total of three Vintage Cards cards so that I could also test how this board sounds in all three (JD-990 can natively import JV-80 patches). But even with two, it’s not a problem I can record everything into MIDI and repeat the test once I place the card into the JD-990.

In any case, we will eventually know how this board sounds in all three synths. Fortunately, there is another dedicated bank just for the JD-990 on the Vintage board, so if you find the JV-80 patches to sound mediocre in JD-990, don’t worry—they weren’t programmed for the JD-990 to begin with and simply move to the JD section of the card.

It’s go time! I’ve connected to the card’s Wi-Fi using my phone and did some basic configuration, like changing the Wi-Fi ID and mode. These steps aren’t necessary—the card works right out of the box—but I wanted to tweak things a bit.

One thing I should point out, since I have a first-batch card, there was a small compatibility issue with the JV-80 and JV-880 (which likely affects the JV-90 and JV-1000 as well). A minor modification was required, which I performed. If you’re buying a card now, there’s nothing to worry about—the first batch is sold out, and the second batch has this issue corrected at the factory. You can ignore this section, but I’m mentioning it just in case someone ends up with a first-batch card. The fix was simple: desoldering one component and attaching a single wire.

Now for the moment of truth. I reset the card and connected to it via my phone, selected the Vintage Card binary I dumped yesterday, pressed upload, and patiently waited. After a few minutes, the board status changed—it was no longer empty. The Vintage Card was now in my JV-80!

Time to restart the card and power down the synth. A few seconds later, the machine rebooted, and the card worked perfectly. I’m now browsing the presets from the Vintage Card!

Where To Get The Card
At the moment of writing this the first batch is sold out. It would be best to reach to the designer via this link or ask folks at the Gearspace forum in this thread.

Sonic difference between E-MU Emulator E4X “Classic” and the Ultra series

Impressed by all the online reviews and claims about the differences between the Ultra and Classic series, I’ve decided to purchase an expansion card for my Ultra. This card features converters from the “Classic” series era and is based on the AD1861 DAC as used in E4X Turbo (this makes perfect sense as this card was originally designed for E4X Turbo). The Emulator Ultra series and the  “Classic” represent two distinct approaches to digital-to-analog conversion, each with unique design philosophies and hardware configurations tailored to their era and application.

Shown in image above, the Emulator Ultra series features a Cirrus Logic CS4329 20-bit DAC with differential outputs. This DAC is based on the Sigma-Delta conversion architecture, a method known for its high resolution and excellent noise shaping capabilities. This approach reduces quantization noise in the audible range, making it ideal for achieving clean and accurate audio reproduction. The Ultra series further enhances its balanced output design by incorporating two OP275 op-amps per channel to generate balanced signals. The OP275 op-amps are well-regarded for their low noise and high fidelity, ensuring that the balanced outputs maintain the integrity of the signal. This setup aligns with professional audio standards, where balanced outputs are preferred for their ability to minimize noise and interference, especially in studio environments with long cable runs.

In contrast, the Emulator 4X “Classic” employs an 18-bit PCM DAC from Analog Devices, specifically the AD1861 (shown in the image above). The PCM conversion approach relies on precision resistor ladders to directly convert digital signals to analog. While this design is less common in modern equipment due to the rise of Sigma-Delta converters, it has its own set of strengths. PCM DACs like the AD1861 are often praised for their natural and musical sound characteristics, offering a straightforward signal path with minimal processing. The 18-bit resolution reflects the technological standards of its time, and although it may lack the extended resolution of modern 20-bit or 24-bit systems, it was more than sufficient for producing high-quality audio during its era. In summary, the choice of converters and supporting components reflects the technological advancements and priorities of the time.

Being such different converters (one PCM, other Sigma Delta) I’ve decided to undertake a small task: browsing the web to find out what people are saying about the difference in sound between the Emulator 4X (Classic) and Emulator 4 Ultra series. The overall “repeat phrase” seems to be:

“The converters on the E4 Classics are better than the Ultras; they sound warmer, and the bass is rounder. Also, the Classic features an R2R DAC, while the Ultra does not. R2R generally means more punch, better dynamics, and an overall warmer sound, with more non-linearity and harmonics in the lower end.”

And now that I have finally purchased this expansion card and completed all of the analysis and tests I can tell you one thing: I wish the above quote was correct, but unfortunately it is not. 🙁

As now I own an Emulator Ultra with the output expansion card PC511 (rev A) – which, as mentioned earlier, uses the same converters as Emulator “Classic”. This means I have access to both generations of converters—the PCM and the Delta converter. I decided to test them both. I really hoped they will sound different, giving me access to two different sonic colors from two different generations of Emulators only to find out they sound exactly identical. The harmonics are the same, the dynamics are identical, stereo separation is the same, etc…

The only difference that was found – Ultra has a better anti-aliasing filter, which technically makes it “warmer” which is a bit amusing as people say it’s the other way round (remember “repeat phrase” quote three sections above?). However, in practice, this makes no difference whatsoever because we’re dealing with frequencies above 22 kHz. In the Emulator Classic, these frequencies are mirrored above 22 kHz, while in the Ultra, they are properly cut as we will show in spectral analyzer below. Now, let’s listen to some examples recorded through each of these converters. Output from Emulator was recorded into RME UCXII at 48 kHz.

Low frequency
The bass sounds exactly the same on both converters. The harmonics are identical when listening on my Neumann KH120A speakers and Beyerdynamics DT880’s headphones. This is also confirmed by the spectrogram shown below as it covers the important bass range from 10 Hz to 1 kHz – the first part of the recording was made on the Ultra and the second half recorded on the Classic, both files normalized and then joined into one for easier analysis side by side. For anyone who has doubts about the accuracy of this information, feel free to download the provided source audios and analyze the data for yourself.

Emulator Ultra: Bass-ultra.wav
Emulator Classic: Bass-4xt.wav

High frequency
Now, let’s take a look at the high frequencies. One important thing to keep in mind is that the source sample was 44 kHz. This means that anything appearing on the spectrogram above 22 kHz should absolutely NOT be there! I deliberately recorded the audio at 48 kHz to highlight the aliasing issue with the Emulator “Classic.”

Up to 22 kHz, everything is absolutely identical. Every individual harmonic or standout point present on the Emulator Classic is also present on the Ultra. The spectrogram below contains the first part of the recording made on the Ultra and the second half recorded on the “Classic.”

Emulator Ultra: Cymball-ultra.wav
Emulator Classic: Cymball-4xt.wav

So where’s the difference?
We have seen thus far that in 0-22kHz range there is no difference in sound and spectra whatsoever. Some may argue, “Perhaps the difference lies not in the frequency range but in subtle dynamics and stereo separation that no spectrum analyzer can capture.” Fair enough. Here is a stereo beat with plenty of dynamics. Can you identify which of the two recordings is from the Emulator Ultra and which is from the Emulator “Classic”?

StereobeatA.wav
StereobeatB.wav

Let me help you: No one can tell the two apart. 🙂

Conclusion
The most important takeaway from all this is simple: whenever someone claims i.e. that an A converter is “superior” to a B, always ask them for actual audio evidence, rather than their impressions and thoughts. This will certainly save you a lot of money. In my case, the expansion wasn’t overly costly, and it might even encourage me to use my Emulator for more serious work. Overall, it turned out to be a positive experience and my Emulator with extra 8 outs has technically increased in value. So nothing was lost in the end.

Yamaha TX16W the hidden gem!

When I first heard the Yamaha TX16W sampler back in 2009, I immediately knew it wouldn’t stay in the sub $50 price range for long. The sound was simply outstanding—rich with character, and the low end was astonishingly powerful! This realization hit me during a quiz posted in 2009 on the Harmony Central forum by Paolo Di Nicolantonio. The quiz presented several options, and I was convinced the mysterious sampler was either the Emulator III or one of the high-end Roland models like the S-750 or S-770. When Paolo revealed the TX16W as the answer, I was completely stunned. I couldn’t believe it! Without hesitation, I purchased one, which at that time was for a little more than the cost of shipping.


Paolo Di Nicolantonio

Paolo, by the way, deserves the credit (or blame!) for this discovery. He runs the exceptional Synthmania YouTube channel, which I highly recommend. At the time, I didn’t know Paolo very well. He looked kind of like Paul Sorvino and I didn’t wanted to critique the quiz, I wondered what if he’s a mafioso, and I didn’t want to end up in the river with a pair of cement shoes. (note: previous sentence is an old inside joke from the ole Harmony Central forum… Paolo is not a mafioso, but a synth enthusiast and a great music tutor). After I submitted the quiz with the wrong answer, Paolo kindly messaged me privately with the correct one. Thankfully, I managed to secure one. Nowadays finding a cheap TX16W for $50 is more less a statistic rather than rule. You might have to prepare the amount of cash that is order of magnitude larger.

Here are a few demos from the quiz. Keep in mind these are mp3 quality, you should really hear one in person. Still I hope they impress you as they did me:

The Character
As opposed to some other 12-bit legends such as the Akai S950 and Roland S-550, the Yamaha TX16W does not darken or tame the sound as the audio is pitched down! This is a crucial point when discussing its character. Rather than becoming duller or less engaging, the sound actually becomes more fascinating as it is pitched down. Examples like Underwater.mp3 and Quadro.mp3 illustrate this beautifully. Instead of losing its edge, the TX16W retains all the sharp transients. But why is this the case?

Let’s start with the Akai S950. When slightly overdriven, its inputs produce a gorgeous overdrive, thanks to its retro PCM converter / electronics, making it perfect for trip-hop and similar styles. However, when you transpose a sample down, the CV signal unfortunately forces the filter to track permanently. No matter how much the filter is opened, the CV overrides and closes it, resulting in a dark, dull sound. All the grit and crunch are lost in the process.

Another example is the Roland S-550, another cult favorite, widely used in early rave and techno tracks. Its “problem” lies in its nearly perfect transposition. When you pitch samples down, they become increasingly round and smooth. This is in stark contrast to the TX16W, which unveils entirely new sonic textures as you lower the pitch. Random samples reveal unexpected patterns and sounds, with harmonics that were originally too high to hear now entering the audio range, preserved rather than smoothed out or filtered away entirely.

And that’s the secret of the TX16W. To quote Acreil from the Gearspace forum, who’s top expert in audio playback of old hardware synths and samplers: “Yamaha (TX16W) uses linear interpolation with 3 fractional bits and (effectively) a 400 kHz sample rate (though it’s actually considerably more complicated than that, and I won’t get into all the details here). This can sound pretty clean if you want it to, but it can also sound extremely nasty if you transpose down a lot—just like all the other AWM models. – It’s mostly the way the samples are transposed. As far as that goes, the TX16W already has a more interesting sound than the Akais.”

The punchy drums
Another fascinating characteristic of the TX16W is the punchiness of its sound when the signal is driven slightly hot into its converters. While this trait is typically associated with the Akai S950, I was completely taken aback when I compared the TX16W to some of the most renowned samplers in this area, such as the E-MU Emax, SP-12, Ensoniq ASR-10, EPS, Roland W-30, Akai S950, S3000XL, MPC 2000XL, MPC 3000, and a few others. In one particularly extensive test involving a sampled breakbeat, I listened with my eyes closed and consistently found the TX16W to be the punchiest. This was surprising, as I never expected it—or at least, I assumed the Emax and S950 would dominate in this regard. Here’s a link to the test—feel free to listen for yourself and draw your own conclusions: Vintage Samplers contest (sound test. comparison)

The secret of its unique sound
As you may know, most hardware and all software samplers use a fixed sample rate and resample data in real-time to transpose the sample. However, some older samplers like Emulator II, Emulator III, Akai S950, Prophet 2000 and Korg DSS-1, employed a “divide by n” technique, which functions like tape playback. In this method, the pitch is altered by changing the speed (or clock), eliminating the need for dithering filters because there is no interpolation—pitch changes occur by directly adjusting the clock speed.

When it comes to the TX16W, things get a bit confusing. It appears to use both techniques to some extent. Let me first quote Magnus Lidström, the author and programmer of the Typhoon, operating system for the Yamaha TX16W:

“The TX16W has a fixed 400 kHz output sample rate and linear interpolation for pitching whole octaves only. It then holds samples for exact pitch within octaves (essentially changing the length of individual sample points). The output filters are pretty sloppy with only 24 dB per octave (18 dB for the individual outputs). Sampling filters are much more impressive with an eighth-order Chebyshev design. Also, the main output DACs are not linear but use a floating-point 16-bit resolution (the individual output DAC, on the other hand, is 12-bit linear).”

Acreil, from the Gearspace forum, provides further insights on this topic:

“It’s super weird and complicated, but great. It generates a variable clock from 25 to 50 kHz and uses that to increment the sample address. The clock is derived from a 400 kHz master clock (essentially the sample rate), so it has a lot of jitter, but unlike a phase accumulator, the period of each succession of 64 (I think) clocks is always constant. So you hear some distortion of the harmonics, but not aliasing per se. Higher and lower octaves are obtained by making the sample address increment larger or smaller, so it sort of decimates the waveform by powers of 2 at higher octaves (the PPG Wave 2 also does this). When the address increment is less than 1 sample, it does linear interpolation with 3 fractional bits. The RX5, TG33, etc., work the same way. The TX16W’s filters are even weirder than that.

The original AWM sample playback engine (used in the TX16W, RX5, RX7, TG33, plus some other stuff that no one cares about) uses what Yamaha called pitch-synchronous sampling. It’s basically what I described earlier in the thread—constraining pitch so that each waveform period is an integer number of samples. At the time, I didn’t realize it, but similar methods were used by Casio, Seiko, and Technics. The sample rate is effectively 400 kHz, generating a clock frequency from 25 to 50 kHz to increment the sample address.

When transposing down, it uses linear interpolation (though it’s quite rough, with up to 3 fractional bits only). When transposing up, it skips samples in powers of 2. Technically, there’s no aliasing, but there are sub-harmonics. Pitch resolution is about 3 cents at any frequency. And it’s got extremely weird time-varying FIR filters, but the effect is rather weak. On the whole, it’s my favorite sample playback engine—both for the sound and because it’s an ingenious technical oddity.”

Upgrades
Due to the large number of online sound banks (I counted a total of over six hundred floppies), including awesome sounding factory disks, I highly recommend installing a FlashFloppy or HxC drive, ideally with an OLED screen (as shown in the image above), again due to huge library it’s much easy to navigate rather than stare at the 3 segment LCD (which I removed and installed an OLED). The main display of TX16W can also be upgraded—in my case, I installed a white-on-black LED screen, which looks great.

One important point to mention is that the TX16W uses a switching power supply, which, as of 2025, needs to be recapped since its components have exceeded their lifespan. I’ve witnessed this firsthand, where at least half a dozen capacitors had dried out.

Lastly, let’s talk about RAM. From the factory, the TX16W comes with 1.5 MB of RAM. Based on my personal experience with my Akai S950 (upgraded to the maximum RAM of 2.25 MB), I would strongly recommend upgrading the TX16W to 3 MB (one expansion module). For more serious work, it’s ideal to have the full 6 MB installed. Since this is a 12-bit sampler, 6 MB is equivalent to having about 9 MB on an Akai S1000, which is sufficient for most use cases. The factory-installed 1.5 MB is adequate for loading factory disks, but for more demanding projects—such as properly sampling a TR-909 or TR-808 kit—at least 3 MB is highly recommended.

Fortunately, there’s a modern solution for RAM expansion. A company called Indigo Audio recently designed an excellent RAM upgrade board (created by Suad Cokljat), shown in the image above. Their expansion is superior to the original, as it draws significantly less current, which helps extend the lifespan of your power supply. The price is also comparable to existing RAM upgrades for the TX16W, making it a great investment.

Finally, the magic number: 3072 kB, or 3 MB, in my TX16W—I’ve been waiting for this moment for so long! Now, I can finally enjoy my MFB-503 sample set and still load a few additional sounds, which was previously impossible. Considering how amazing this sampler sounds, I doubt I’ll stop at 3 MB.

Another important reason I recommended FlashFloppy earlier has to do with saving. Let me give you an example. My MFB-503 set, which I sampled, edited, and programmed on the TX16W,  occupies two floppy disks. This is because the TX uses SD (single density) disk format which is 740 kB. Now imagine saving the fully expanded 6 MB RAM onto floppies. This could take as many as 8-9 disks, depending on the number of programs and samples. At the very least, it would require 8 floppies. This is where FlashFloppy becomes essential.

The image above shows the newly installed 1.5MB expansion. It stands firmly and does not wobble. As of the floppy emulation. For those nostalgic for the ‘vintage’ floppy experience, you can even add a small piezo speaker to emulate the sounds of head movement. FlashFloppy natively supports these classic “clicks” and “zaps,” and I’ve installed one myself for that authentic retro touch.

Operating system
One of the most talked-about aspects of the TX16W is its operating system. Yamaha’s original OS was considered unintuitive and clunky, leading many users to struggle with its workflow. Navigating through the menus required patience and a thorough understanding of its manual, which could be a steep learning curve for beginners.

Fortunately, a third-party operating system called Typhoon 2000 was released later, dramatically improving usability. Typhoon streamlined the interface, making sampling, editing, and playback more straightforward. Many modern enthusiasts recommend using Typhoon for a smoother experience with the TX16W.

Conclusion
Sonically, the TX16W is a true gem! Nothing else sounds quite like it. No other sampler features this unique playback method, and the way harmonics emerge during transposition is pure magic—almost as if it sings on its own. It can proudly and confidently hold its place in your rack alongside any of the big names, like the ASR-10 or the Akai S series.

Library
Let’s not forget the huge library for the TX16W that is available online from various sources. Eventually, I ended up with 630 disk images, which is why the FlashFloppy/Gotek solution is a must. Below is a screenshot of the library I’ve compiled for my Yamaha. Using actual floppy disks for this would be impractical.

Regarding online resources, there’s one important thing to understand: Yamaha uses a (PC) DOS-style disk format. Some of the floppies you find online may be in the form of a folder. To create a disk image from such folders, there’s a great tool called TX16W Floppy Baker, which is available here.

I’m unsure of the legal status of Yamaha’s library, which is why I don’t share my collection. Besides, I built it the same way you can—by downloading zip files, extracting them, selecting the folder content for each “disk,” and sending it to the Floppy Baker. I know it’s a lot of work—I’ve been through it—and after 2–3 days, you’ll have a complete library in .img format. If you’re not keen on building the library yourself, there are other sources that provide precompiled images you can put directly onto a USB stick. However, I can’t guarantee those will include everything I have, or vice versa. Each entry you see below represents one floppy image created using the Floppy Baker utility. Happy disk hunting!

Typhoon OS
If your Yamaha TX16W still uses a floppy drive, you can load Typhoon 2000 from here. However, if you’ve already upgraded your TX16W with a Gotek floppy emulator, I’ve prepared an archive that will save you hours of work. (Typhoon is not originally in .img format, and extra software is typically required to install it, etc.). This archive contains the Typhoon OS converted into a floppy image, along with two configuration files. Place all three files in the root directory of a FAT32-formatted USB stick. You can also edit the FF.CFG file to adjust the speaker loudness or change the display type. Currently, it’s set for an OLED display, but you can change it to a 3-segment LCD if needed. The archive can be downloaded from here.

Akai S3000 vs S3000XL the ultimate test – which is “better”?

The Akai S3000 and S3000XL samplers, iconic fixtures in the music production landscape of the 1990s, revolutionized the way musicians and producers approached sampling and sound design. Renowned for their robust build, intuitive interface, and unparalleled sound quality, these samplers became staples in studios worldwide. The S3000, introduced in the early 90s, quickly garnered acclaim for its versatility and expansive feature set. The subsequent release of the S3000XL built on this foundation, offering enhanced functionality and greater ease of use. Together, these models not only defined an era of digital sampling but also influenced a generation of artists, shaping the sounds of genres ranging from hip-hop to electronic music.

Simple Test
However, despite their shared legacy, various myths have emerged online, with debates over whether one model is superior to the other in terms of playback sound quality. To address these claims, the most straightforward approach is to conduct direct comparisons. Audio enthusiast Tech44 from the Gearspace forum undertook this task, leveraging his high-level expertise and high-quality audio equipment to ensure accurate results. Tech44’s method was meticulous: instead of merely playing loops through each sampler, he loaded individual samples into both the S3000 and S3000XL and then sequenced them back via MIDI. This approach provided a real-world application scenario, allowing for a true comparison of their performance and sound reproduction capabilities. This article delves into the history, features, and lasting impact of the Akai S3000 and S3000XL, and presents Tech44’s findings to determine if there is a definitive answer to the debate over which sampler truly reigns supreme. A simple A vs B test was created from his recordings by splicing the two samplers back to back. For those curious or who want to analyze the data themselves here is an audio recording of one sampler followed by the other:

S3000 vs S3000XL.wav (24bit, 44kHz audio file in uncompressed wav format)

On the Gearspace forum in “All Akai’s are sexy thread” we posted this audio file above. There people were required to tell which part of the recording is S3000 and which is S3000XL. Out of 750 downloads a total of 0 correct answers were given. Let that sink in. 🙂 At this point we could simply end the article, because regardless of your listening environment I think it is clear you will be unable to tell which is which. However, let’s dig a little bit deeper, since we want the final truth.

Advanced Analytics
“But wait, they must sound different I’ve read it on the internet…”. Alright, folks. Since on the Gearspace forum we already determined that us humans can’t tell the difference between the S3000 and the S3000XL as nobody was able to pinpoint exactly which sampler was at certain point of the recording. Time to call in the big guns: computers! Inspired by someone’s astute observation that the S3000XL sounds like it was made out of Legos (it sounds plastic), I present to you our thrilling new saga.

Finding the plastic: Volume 1 The Quest Begins
First stop: the low end! If I were plastic, that’s where I’d hide in between 20-350 Hz. Let’s compare the S3000XL on the left and the S3000 on the right. Click the image for full size. Hmmm… the spectrograms look identical. Well, that’s a bummer.

Wait! If it sounds plastic, it must be in the highs. Let’s crank it up to -120dB, and go to high frequency, and I mean extremely high in 17000-22000 Hz where only dogs and bats dare to listen. Click the image for full size. Aaand… nothing. Spectrograms still look the same. S3000XL on the left and the S3000 on the right.

You know what. Now when I think of the plastic and frequencies involved in the sound. Of course, plastic would be in the midrange. How did I miss that? Let’s check it out. Left: S3000XL, right: S3000. But no, they look identical in the 1-5kHz range.

Finding the plastic: Volume 2 The Plot Thickens
And then it hit me, like in that movie, “The Usual Suspects.” When you can’t find the tiny details, zoom out and look at the big picture! So, let’s zoom out and search for plastic artifacts. Nope. Spectrograms are still twinsies. Left: S3000XL, right: S3000.

Hey plastic! Where are you hiding?
Just as I was about to throw in the towel, a lightbulb moment! If it’s not in the signal and in the things we hear, then it must be hiding deep in the noise. Right! Let’s amplify the range a gazillion times and inspect the background noise. Aha! The plastic has to be there. Somewhere! Elsewhere? Nowhere! Left: S3000XL, right: S3000. Spoiler alert: still nada.

The verdict
Despite rigorous tests showing no difference in sound between the Akai S3000 and S3000XL samplers, many users continue to believe that one sounds better than the other. This phenomenon can be attributed to cognitive bias, specifically confirmation bias and the placebo effect.

This occurs when people favor information that confirms their preexisting beliefs or values. If a user believes that older equipment, such as the S3000, must sound better due to its higher original cost or its vintage status, they are likely to interpret their listening experiences in a way that supports this belief. They might ignore or downplay evidence that contradicts their preconceived notions, such as blind tests showing no discernible difference in sound quality. And this takes a LOT of effort especially once the evidence starts pouring in.

When we say rigorous tests, we mean EXTREME rigorous in 24 bit domain which offers 140 dB of headroom for analytics where human ear is not even capable(!) to analyse anything to begin with. This is why he have computers. And they say: no difference whatsoever. And it makes sense as we will touch this subject in the chapters below as they are crucial in understanding the whole picture. One thing to remember from all of this:

Do not believe the myths coming from random nobodies on the internet. Instead, prioritize relying on empirically supported data that is open to personal analysis. Should you lack the necessary expertise to conduct such analysis, it remains prudent to refer to authoritative sources. This particular article presents the results of rigorous testing and includes access to the raw 24-bit data, enabling independent verification and analysis. This article was not written for those individuals with cognitive bias because they already made their mind and any attempt into changing it is a waste of time. The more evidence you present them, the more faster they change the goal posts. Instead of ending the article here, and especially if you are interested in buying any of these units, or it was in fact the reason you visited this article at the first place, we will include a few chapters that could help your decision and even include a few FX and resonant filter demos.

So, which model is for you?
One important consideration is RAM. If you plan to upgrade S3000 expect to pay $150 (May 2024) for 8 MB expansion. If you plan to upgrade S3000XL, expect to pay $15 for 16 MB expansion. This extreme difference (1:10 ratio) is due to the fact that S3000 uses proprietary RAM while S3000XL uses 72 pin SIMM which is cheap as the postage cost itself.

It should be noted that the S3000 comes with a built-in effects processor, while the S3000XL does not. Instead it requires an additional effects card, the EB16FX, which has become increasingly difficult to find these days. The S3000’s onboard effects include Echo, Chorus, and Pitch Shift. In contrast, the EB16FX board for the S3000XL offers a more extensive array of effects: Echo, Chorus, Reverb, Pitch Shift, Distortion, EQ, Ring Modulation, Flange, and Phaser. This means that an S3000XL equipped with the EB16FX board provides a much larger palette of effects. So if you are after a known artist for whom you know used S3000 and its internal FX, then go with the S3000. If you just want that S3000 sound for basic playback, then it doesn’t matter, you can pick either of the two. If you have EB16FX board in your MPC and looking to add a hardware sampler, then S3000XL would definitely be a better choice.

Not only does the EB16FX board expand the variety of available effects, but it also enhances the flexibility of their application. The EB16FX features two parallel multi effects blocks, each capable of handling any of the effects, plus two additional effects blocks dedicated to reverb. This configuration allows for a total of four parallel effects blocks, offering a significant advantage in terms of creative possibilities.

While this article does not delve into a comparison of the quality of these effects or the differences between the S3000 and S3000XL in this regard, we acknowledge that this is an area of interest for many users. For those curious about the sound of the EB16FX board, we will provide demo recordings in the addendum. These demos aim to showcase the capabilities of the EB16FX board, offering listeners a chance to hear the effects in action and form their own opinions.

Moore’s Law
There is a common concept that older equipment inherently sounds “better”, maybe it does, but when comparing the Akai S3000 and S3000XL samplers this is a flawed starting point. Because both models featured absolute state-of-the-art converters at the time of their release, representing the pinnacle of audio technology. Converter is not just one single IC but the entire circuitry dedicated for recreating digital signal in analogue domain. It is unfortunate that people focus on a single chip, rather than entire board that is delivering the actual waveform.

When the S3000i was introduced, it came with an internal drive and maximum memory capacity, and it could cost close to $10,000 with all expansions —a staggering price that reflected its cutting-edge capabilities and premium components. The period when these samplers were released was marked by significant breakthroughs in semiconductor technology, with Moore’s Law driving rapid advancements. This meant that just a few years later, the S3000XL was introduced at a much more affordable price point. The key difference was not in sound quality but in technological advancements and cost efficiencies. Unlike the S3000, the S3000XL no longer required expensive proprietary Akai memory. Instead, it used more affordable 72-pin SIMMs, which had become widely available and inexpensive due to the booming computer market.

Additionally, the S3000XL benefited from more powerful CPU resources, offering better performance for a fraction of the cost of the S3000. This drastic reduction in price, due to cheaper memory and improved semiconductor technology, often leads to confusion when people compare the original release prices of these two models. It’s important to note that despite the lower cost, the S3000XL was still a significant investment, unaffordable for an average school kid at the time.

Understanding this context is crucial for appreciating why the S3000XL could be sold at a lower price without compromising on quality. The advancements in technology allowed for more efficient production and reduced costs, making high-quality sampling more accessible to a broader range of users.

The history
When the Akai S3000 was released, it represented the ultimate goal for every serious music producer. Owning an S3000 signaled that you had truly “made it” in the industry. Its cutting-edge technology and superior sound quality set it apart from competitors, making it a coveted piece of equipment. Producers with an S3000 knew they had a significant advantage over those still using older models like the Roland W30, Akai S950, Roland S-550, or even the Akai S1000. There was simply no comparison to the superiority of the S3000 when considering the context of that era. Among other things it finally gave the Akai S series a resonant filter and we will actually demonstrate some of it on the later S3000XL model in the demos below (in the addendum of the article).

The prestige of the S3000 was such that people would go to great lengths to acquire one, including taking out loans. This sampler was more than just a piece of equipment; it was a serious investment in one’s music career. Owning an S3000 meant you were a serious player in the game, with tools that could outperform nearly anything else available at the time. Its powerful features and unparalleled capabilities made it indispensable for professional music production, and having one in your studio was a clear indication of your commitment to quality and innovation in music creation. A few years later it was replaced by S3000XL with the same impressive specs. First units of S3000XL were assembled in Japan, while the later were assembled in China. They all feature exact the same internal boards that were made in Japan. In the two images below we can see the inside of the unit that was assembled in Japan and below it the inside of the unit that was assembled in China. They both contain the same PCB’s which say made in Japan.

ADDENDUM:

Akai EB16FX board – the demos with S3000XL
First a small disclaimer. Don’t let it fool you, but EB16FX can be a bit frustrating at times, since all of the effects are routed through the main output. Also while containing some very useful effects, you will find yourself using it at only 50% of its potential. Because the board is split into 4 effects groups that run all the time in parallel. So if you use effect A it will take the whole headroom and you are forced to mix it internally with effect B. As a result you start using only effect A, because both effects at once can turn into mud, while all 4 effects can create a lot of mess. With that being said it is possible to use them all at once. But in most situations the half of DSP chip will be twiddling thumbs – doing nothing.

In my opinion, what they should have done was to use ALL of the DSP power and gave us one multi effect plus one reverb. As a result the board would have twice more fidelity, more quality, dynamic range, bandwidth etc. If it only had one proper effect rather than 4 at a time and employ full DSP power for that effect, it would be excellent addition. Because algorithms are quite good. There is: distortion, EQ, ring mod, chorus, flange, phaser, pitch shift, pan mod, delay and reverb.

The board can look absurd at times, because in effects A and B you already have reverb option, while C and D are reverbs only. So you end up having a possible scenario where you were supposed to Mix 4 different reverbs, all internally in digital domain and all streaming that through one set of stereo outs. This is an early 90’s 16 bit device, and not your DAW where you can mix things with near infinite bit depth. But it is what it is. Let’s hear some of the effects in a few demos. Sorry these were made under 5 minutes, so don’t expect some hit music in here and pardon the mp3 audio quality. Sources of the four demos below: All internal synthesis (internal waveforms only), no external samples used (except for drums). Internal effects only (EB16 effects board).

Analogue Pad – demonstration of a wide EB16 chorus.
Ring Modulator Arpeggio – excellent ring modulator for Techno!
Bass and Arpeggio – demonstration of envelopes and resonant filter performance.
Saw Line Flanged/Delay – another one, but with cool flanged delay.

Extreme low (filter test):
Filter open/close – loop processing. I hope you have either large speakers or good headphones that go well below 30Hz. This is extreme low end, particularly towards the end of recording, yet full of power, earth shaking. Absolutely fantastic sounding filter. Hint: try this on other samplers. Only a few can do this kind of low end!

Well that kinda wraps it all up. I hope that you enjoyed the article.

Or if you just want to share your anecdote, again feel free to comment!

Finding the tightest MIDI sequencer among a dozen (measurement tests)

Hardware MIDI sequencers have a rich history rooted in the evolution of electronic music technology. MIDI, or Musical Instrument Digital Interface, was introduced in the early 1980s as a standardized protocol for electronic musical instruments to communicate with each other.

The first hardware MIDI sequencers emerged around the mid-1980s. Devices like the Roland MC-500 and Yamaha QX1 were among the pioneering standalone sequencers. These early models allowed musicians to record, edit, and playback sequences of MIDI data, enabling them to control multiple synthesizers and drum machines in synchrony.

Throughout the late 1980s and 1990s, the market saw significant advancements in MIDI sequencing technology. Companies like Roland, Yamaha, Korg, and others introduced sequencers with improved features such as more tracks, better editing capabilities, and enhanced integration with other MIDI devices.

In the late ’90s and early 2000s, hardware MIDI sequencers experienced a shift with the emergence of computer-based DAWs (Digital Audio Workstations). These software applications offered more comprehensive recording, editing, and mixing capabilities, challenging the dominance of standalone hardware sequencers.

However, hardware sequencers persisted, appealing to musicians seeking tactile interfaces and dedicated performance tools. Companies continued to innovate, releasing units like the Elektron Machinedrum and Octatrack, Akai MPC series, and newer versions of the Roland MC series, offering unique sequencing approaches, sampling capabilities, and real-time performance features.

Fast forward to the present day, hardware MIDI sequencers remain relevant in the music production landscape. They often integrate modern features such as touchscreen interfaces, advanced MIDI capabilities, CV/Gate outputs for analog gear, and innovative sequencing methods, catering to the preferences of various musicians, producers, and live performers.

The evolution of hardware MIDI sequencers showcases a journey from the early days of MIDI technology to the present, where they continue to carve out a niche by combining the hands-on approach of hardware with the power and flexibility of modern electronic music production. But which is the tightest midi sequencer? Let’s build some custom cables and run some measurement tests to find out!

In this article the following devices will be tested

Hardware sequencers:
Akai MPC2500
Kawai Q-80 EX
Roland MC-500MkII
Yamaha QX3
Yamaha RS7000

Hardware keys synths and samplers featuring a sequencer:
Ensoniq ASR-10
Ensoniq ESQ-1
Ensoniq TS-10
E-MU Emulator 4 Ultra
Korg 01/W
Kurzweil K-2600 RS
Roland XP-50

Computers featuring sequencer software:
Amiga 500
Atari 1040 ST
Mac running OSX and Windows 10 using RME UCXII and MPC Renaissance

MIDI Jitter
MIDI jitter refers to variations or deviations in the timing or regularity of digital signals. In the context of MIDI jitter can disrupt the accurate reproduction of the original signal due to timing inconsistencies. In data transmission, it can affect the timing of bits being sent across a channel. Jitter can arise from multiple sources. It might occur due to imperfections in the clock signal, signal interference, signal reflections, noise in the transmission medium and limitations in the precision of the components or the timing of the system.

In case of computers we need a perfect and dedicated USB bus that will not be interrupted by other protocols and services, which at some systems can be a difficult task to do (i.e. Windows 10 based computers). If the same USB port is being interrupted for some random reason every few seconds it will definitely have less “space to breathe”. Which brings us to the last parameter and these are drivers. So even if we are limited to i.e. the Win10 system a set of good drivers can improve things a bit. Looking at the graph with the results some might notice that Akai Renaissance is missing in the graph. The reason for that is, it would simply not fit, or if it would fit, the rest of the graph would be hard to read. This is a clear example of good vs bad drivers, in this case the RME vs Akai.

Measurements
All of the measurements were performed on a free software called MLA – MIDI Latency Analyser v2.1.1. It’s a piece of software to help us determine the effects that hardware, driver and software changes have upon MIDI latency and jitter. The program is also handy for identifying the ideal number of samples of offset to apply to MIDI tracks to compensate for round-trip latency when recording them to audio tracks. I am not the author of this software not related in any way to it, therefore I can not provide any sort of technical assistance regarding this software. A special hardware cable is required to be built before using it. If you decide to join the research, all of the details can be found on this address: http://tinyurl.com/midijitter

Offtopic: Some extra scores and some explanations
Yes, many of the keyboards feature hardware sequencers. This is why I included many of the hardware keyboards / synths into the measurement. I believe Ensoniq ESQ-1 was one of the first ones with a decent sequencer. It’s a pity it does not have some more features like setting the fixed velocity onto the recorded data or modifying the gate times. This is also the reason an additional (Features) column was included in the results table. Point is, if just because some sequencer scored high, does not mean you should try to grab it immediately, then send me 50 emails cursing me why didn’t I tell you the sequencer has nothing useful inside. This is the reason a scoring column called Features was added and it works on the following principle (how the scores are added). Please note the Features score column DOES NOT in any way relate to the MIDI jitter measurement results. If you’re curious here’s how the Features scoring column works: 

20% score = bare minimum Record, Play, Transpose, Quantize, Copy, Paste
+ 20% for advanced MIDI editing, change velocity, gate, note editing ranges
+ 20% for step recording
+ 20% for microscope edit
+ 20% for XoX style edit

So a sequencer that scored 100% has all of the above. Again this is just to make your potential shopping list easier, has nothing to do with the MIDI jitter results. And yes some of the rack synths and samplers have sequencers too! So they are included as well.

Atari vs Amiga – the final battle, which is better for MIDI?

To answer another potential question: Why including computers in the article titled hardware sequencers? As a reference point. Nothing more. Sort of to see where you stand if you run any of the computer + audio interface combos mentioned in this test. We will also have a privilege to see the battle of two 16 bit legends, the Atari 1040 and Amiga 500. For this test Amiga was running the M.E.D. software tracker, while Atari was running the Cubase 3.0.

Results
Before looking at the graph and the table one thing to keep in mind, the smaller the number, the better the result. Ideal number in this case is 0, but we didn’t test Expert Sleepers in here, so above 0 it is. First and top of the table we have the incredible Ensoniq TS10’s. These results and numbers are ridiculous, I agree. I repeated the test several times thinking I did something wrong. Even re-soldering the cables. The number are correct, TS10 has incredibly precise sequencer. On the second place Emulator 4 stored pretty impressive, but unfortunately has a very limited sequencer, so beware. As expected the Atari as a rock solid MIDI standard still stands well, so nothing special required to be said about it. Roland XP-50’s powerful 32bit RISC processor clearly shows up, with results even slightly better than Atari if we include the Max jitter (the max amount a note will deviate from the mean value). Another interesting “battle” of the grooveboxes, Yamaha RS7000 vs MPC2500. Yamaha came out far superior. Or did it? Check out the next chapter titled Individual MIDI hardware outputs vs Jitter as the things are not always as simple as 1+1.

Continuing with the graph we see the regular Mac computer running OSX Sierra connected to a RME UCXII. The results are essentially identical to the Atari. Something that can not be said for the same computer running Windows 10. While the average jitter results are fine, in the sub 1ms range, for some reason a few of the MIDI notes will jump as far as 3ms to the front or back. Don’t worry an average listener won’t hear it, in fact no one will, however if you layer percussive sounds on top of each other then a transient jumping back and forth 3ms (6ms in total) can be very annoying at times. Now keep in mind these are RME drivers (probably the best in the world!). But to see how bad things can go with Windows 10, see the entry in the table that says Akai Renaissance (hint: it’s on the bottom). This is an example why Mac dominated the DAW all of these years, at least for people who run external gear. With MPC Renaissance having plus minus 8, that’s 16 mili-seconds combined, that’s something even a non musical person can hear, say you lay down a pattern of 1/16th hats, this kind of deviation is way too easy not to miss. So yeah, Windows 10 and external MIDI gear, not my first recommendation, or if you have to, go RME interface. I should point out MPC Renaissance was tested only as a MIDI output interface, not as a software per se, and was running Reaper DAW for the test.

I know, you can’t see a thing. Please click on the graph to enlarge it.

Continuing with the graph we see the Korg 01/W which has an excellent sequencer (actually I tested the 01/RW), packed with features almost as much as Roland XP-50 (the later is slightly superior as it has RPS realtime phrase feature which speeds up things quite a bit). 01/W is closely followed by Yamaha QX3, a super complicated sequencer, at least for me who never worked on it before, so it can be very confusing. It looks cool though and is super tight. Next surprise was ASR-10 – it’s literally on a level of QX-3 and QX is a dedicated hardware MIDI sequencer just for that. I was quite surprised as I remember having some reserved thoughts for its song mode so I tested it as well. And I was right, after measuring ASR’s sequencer in song mode, the performance unfortunately drops. I didn’t want to include the data in the table, because most of the people use it in regular pattern mode. For those interested, in song mode ASR-10 is 0.347ms average jitter and 2.7ms max jitter putting it just slightly shy of MPC2500.

Next on the graph we have the Amiga. A cult 16 bit machine that was most of the time used for “tracker” music but had a MIDI option using the serial port interface. The results are solid, but I never expected them to be stellar as Amiga has a set of many chips inside that require a lot of coordination – it was designed as a multimedia system. And this is where the sub 1 millisecond range ends and we are entering past 1ms area starting with Akai MPC2500 and Kurzweil K2600. I was actually surprised to see Kurzweil in here, I was expecting it near the top as Kurzweil is known for its “best of everything” approach. Followed by Ensoniq ESQ-1, and Kawai Q-80EX. Last but not least of the hardware sequencers listed in here came the Roland MC500 MkII. Espen Kraft has a cool video on YT check it out. It will throw away a note or two as far as 2.5ms, but for the 80’s soundtrack scores, it will do just fine. There is something magical about those tactile switches and the fact everything is there at a press of a finger, although it can go deep in microscope edit, hence good marks on the scoring table. The graph ends here, and is missing the MPC Renaissance for the reason already mentioned.

Individual MIDI hardware outputs vs Jitter
Akai MPC2500 has 4 MIDI outputs while Ensoniq TS10 has single MIDI output. So if you want to run 4 external devices with the MPC2500 you will still get results that are shown in the table, which is something that can not be said for a TS10 despite being far superior. Speaking about MIDI chaining, first of all, each additional device in the MIDI chain will add 1ms of delay, some might add even more and some might add totally useless data to their MIDI thru port. For example if you have a Yamaha TG-33 never place it as the first device in the chain, it will make the rest of your day pretty miserable. To avoid MIDI chaining problems you will need a MIDI patchbay. But then keep in mind the second part, which is that all of the output data still has to pass through one single MIDI port of our main sequencer on TS10. While 31.25 kilobits-per-second (Kbps) seems enough for a couple of MIDI notes, the moment you start sending control CC messages for several external moduiles you will soon reach the bottleneck of your MIDI interface. This is why a MIDI device with 4 hardware outputs, will in many cases or always be superior to a single MIDI port connected to a patchbay. My point: don’t dismiss the MPS2500 because of its position in the table, or think that TS10 will solve all your sequencing needs just because it is first on the list. Increasing the number devices chained to the single MIDI output will increase the MIDI jitter related issues, as the data will be more and more packed where there will be no more space left, and jitter will literally take over at one point.

Demos of a few dozen hardware Reverbs

Far from any scientific or “professional” test, this is just a quick bunch of demos when a reverb is pushed a bit harder, say into the 10 second decay time and only around* -6dB below main track. Don’t use it as a reference because results will vary depending on the recording levels at – take it with a grain of salt. All tracks encoded to FLAC (lossless format). Feel free to share if you find it useful.

Regarding the Akais, both of my units are expanded with their respective FX boards (it is not the same FX board as they are many years apart) and they can be used as a regular effects processors, while Kurzweil has a sampling board which again turns it into an external effects processor (it can do way way more than just a reverb, think of it as Eventide’s little brother). I no longer remember why I recorded two reverbs from PCM-70. I guess I wanted to display it’s less chorusy side of things and more closer to the rest of the bunch.

*yeah, some reverb tails might be a bit off. I actually mixed everything on an analogue mixer during the period of a few days, so probably some are louder than others. Sorry about that!

Bonus:

Roland JD-990 revolutionary concept two decades later

It’s been 22 years since its release and the unit is still going strong. Even the latest in Roland’s series, Integra is in fact based on the DNA of the legendary JD-990. But let’s get back in the the 90s for now and see how it all happened. First of all, it should be noted that when model 990 came out, market (at least the Roland’s portion of it) was already dominated by the JD-800, D-70 and the quite popular JV-80 which came year earlier in 1992. Being there at that time i can tell you we considered JD-800 as a Rolls Royce, way out of our reach, but JV-80 was definitely second best, and it sounded incredibly good (for that time) with nice juicy digital resonant filters, for all of us who were into electronic music back then. Just a year later 990 came out. But for some reason it went under the radar for the most of us. It was mostly taken by studios and the pro’s. Little did we know how powerful this synth was (internet was very limited back then, there was no such thing as Gearslutz) while reading some brochure isn’t going to tell you much about it neither.

In fact it wasn’t until JV-1080 which came year later that everyone turned their heads into the direction of Roland with a big wow(!) all over their face. For start it was one of the first synths with 64 polyphony and we were all ready to sell our kidneys to obtain one. The JD-990 came out in kinda unlucky moment, jammed in between JD-800 release in 1991 and JV-1080 released in 1994 it somehow remained unnoticed by many. While those who have heard of it assumed it was just a module version of the JD-800. And because in 1994 we already had 1080 on the market, there was nothing to think about – go for the JV-1080! (myself included)

But there was another group of people, like film composers, producers, you know people who can recognize certain things such as good audio quality right away. Many of them kept their JD-990 despite JV-1080 being the star of the show with all the spotlights focused when it came out. The reason was simple: JD-990 was soundwise class above 1080 and those who had it didn’t want to let it go that easy. Technical differences between 990 and 1080 are explained here. Unfortunately JD-990 wasn’t perfect and had some drawbacks compared to JV-1080 which is why some studios and composers decided to use both (such as for example Vangelis did). Drawbacks are obvious smaller waveform ROM content compared to 1080 ROM, and nasty digital distortion at higher resonance values. This is why in model 1080 Roland implemented variable waveform gain to avoid such scenarios happen ever again (unless you intentionally want them).

It is a know fact that Super JV’s architecture is based on the JD-990. On top of that it comes with the same type of aggressive filter (as opposed to other JV series like JV-80, JV-90 and JV-1000 which had mellower filter resonance) and it came with the now legendary “structures”. When the XV series came out, Roland continued the DNA line of the Super JV. The only thing “different” was that its SYX patch data was based on JV line of synths. Hence why XV can normally load Super JV patches via sysex, yet is unable to load the JD-990 patches. Then the Fantom came out, which again is based on the same concept. And now we have the Integra, which continues where XV series left, maintaining full compatibility and architecture of the Super JV. All of these synths are based on a revolutionary concept of a JD-990 synthesizer. And this is what makes it so special, along with its wide lush sound.

While a lot of extras were added with XV and Intergra series, the core structure is based on what was originally designed in a JD-990 synthesizer. Some may ask, ok but where is the JD-800 in all this? Well, the truth is, it has nothing much to to do with JD-990. It can be described as a D-70 with sliders on it with only difference of having a new effects processor and tones which are now part of a patch, and no longer separate thing. But when it comes to 990 these two synths have practically “nothing in common” except the first 108 waveforms and the mentioned JD effects processor which consists of two blocks. I will now list all the additions that 990 gave over the model 800:

  • Wave ROM was expanded to 6MB (vs 4MB on JD-800) with 195 PCM waveforms (vs 108 on JD-800).
  • Pan inside each Tone was added. On the JD-800 you can NOT pan individual tone for wide stereo sounds.
  • Matrix modulation was added on the JD-990. Let’s explain this – on JD-800 you can’t: increase cutoff point of Tone 1, decrease cutoff of Tone 2, increase resonance of Tone 3, decrease pitch of Tone 4 – all at the same time by moving the modulation wheel.
  • Multiple sources for the same destination added. On JD-990 you can for example use two different LFOs for the same destination – i.e. pitch, filter, TVA. This can create complex modulations. On JD-800 you can only use one source for the same destination.
  • SR-JV expansion card support. Next to standard JD-800 series card slots, there is additional card slot to use a 8MB expansion boards from SR-JV series. (i.e. Vintage Expansion, Orchestral, SFX, etc.)
  • Roland JV-80 patch import.
  • The LFO section has additional waveforms: sine, trapezoid and chaos.
  • Osc Sync function was added. It lets you synchronise two oscillators – a feature found in many analogue synthesisers.
  • FXM was added (Frequency Cross Modulation) – again found in some analogue synthesisers. It has 8 positions (labelled Color) that actually control the frequency of the modulating signal, and a depth setting 0 – 100 that controls the amplitude of the modulating signal.
  • Ring Modulation, for creating all kind of metallic percussion and strange effects.
  • This synth features 6 types of ”structures” which among many other things let you stack two filters in series, for building complex filter textures.
  • 24 dB filter (using structures), next to standard 12 dB which is always available.
  • Outputs increased to 8 total.
  • Polyphonic portamento.
  • Tempo MIDI sync delay.
  • Analog Feel. Which adds a random modulation to the sound to recreate an analogue synth’s “drift”. Not just on the pitch, but varying amplitude also.

Some people asked me about my opinion on JD-800 so I will give it just a brief info on why I initially didn’t became an owner but later I did. I’ve played JD-800, really liked the UI, thought of buying it, but got distracted by the fact there’s no even basic modulation matrix i.e. you can’t set modulation wheel on JD-800 to open the filter and apply some resonance. In fact there’s no even mod wheel on JD-800. Also, all the modulation buses on JD-800 are pre routed. You can’t use two or more sources to modulate the same destination (for complex modular style modulations). On top of that JD-800 is monaural per patch, there’s no pan feature per individual tone – so you can forget wide pads evolving through stereo field, which is a signature of many JD-990 sounds. However as time went by I eventually picked JD-800 as a sort of experiment. The idea was to record a sequence then to use sliders to modify some parameters of  the Tone 1 and record it into the DAW. Then to overdub the sequence but now to modify parameters of Tone 2. Important thing to note here: all of these parameters from JD-800’s front panel are being sent and recorded as MIDI into a DAW. These can later be fine tuned using editing tools on the computer and then finally data thinned before being sent back. This process can be repeated almost indefinitely with MIDI’s own maximal bandwidth (31kbps) being the only bottle neck in here. Using this method you can create very expressive soundscapes where you literally control every parameter in real time. In fact you can overdub every single parameter of every single tone realtime, although at this stage I think the MIDI notes would become quite sluggish due to before mentioned data bottleneck. This fun experiment made me started to like the JD-800. The second thing that I liked  was the fact, with that nice UI, it kinda makes you want to tweak it all the time. All in all I am now a happy JD-800 owner.

Ensoniq TS-10 wavetable and wavesequencing monster

9403

If i would have to choose one ROM-pler to hit the category mysterious, it would definitely be TS-10. First of all i never understood why such high second hand market price (particularly in States). You would think it is because from the impressive synthesis capabilities of having both the wavetable and wavesequencing synthesis in one machine. But i am 99% sure that is not the reason. Even today (writing this in dec/2015) and good condition TS-10 unit can set you back over $1000 USD. Which is in a way funny because in Europe you can obtain it for around 400 notes or ever less if you look long enough. Unfortunately i don’t know the secret connection of the TS-10 and US, if someone does, feel free to add a comment. Personally I suspect the secret is: 1)polyphonic aftertouch; 2)session gig players who got used to it; 3) excellent build quality; 4) excellent sequencer (again gig players territory)

With TS series, Ensoniq continued their line of transwave synths, this time introducing the sample playback in the synth engine. The first thing user would check when exploring waveform content are the transwaves. And unfortunately all those good transwaves from SD-1 are gone. In fact, this synth has a weakest set of transwaves, of all Ensoniq’s transwave series. There is total of just 8 of them. But the worst thing is, they all sound almost the same. So, on the first sight it appears this is no good synth for transwave fun, right? Well…. wrong! We got some good news.

Sample playback in TS series is not just ‘basic playback’, but it also features transwave synthesis. If you load a transwave into TS-10, you can change its properties from the basic waveform into the transwave. Now all that is left is to route a controller (LFO, env, mod wheel, etc.) on to it and your transwave is ready for fun. And we got some more good news.

Since transwave synthesis requires extreme playback precision the same can be applied for basic samples (non transwaves). You can for example use extreme short loop points, and route sample end position to mod wheel. As you move the mod wheel, new harmonics are being generated. This works best on short, white noise samples. Or instead of mod wheel you can use random LFO for some really unique effects.

Another good feature this synth has, is that you can shift the loop point and ‘browse’ through various regions of your sample. This works best on complex samples, made from small snippets, vocals for example (connected in series) merged into one large sample. Route LFO or mod wheel and you got some of the craziest vocals at the output. Believe it or not, but even some high-end professional samplers do not have this kind of loop shift feature. Now you might ask – is this all we can do with it? What would happened if we would have one sample made of 64 or 128 small short (pure waveform) samples, connected in series and then we would apply a loop shift feature onto it? Ever heard of synths such as PPG or Waldorf Microwave? Well, that is exactly what they do! Welcome to the…

Wavetable synthesis. Although not from the default state available on TS series, is possible, once you build a wavetable. Technically speaking, TS-10/12 does feature wavetable synthesis, but unfortunately there is no Ensoniq software for creating custom wavetables so one would need to make it ‘manually’ with standard waveform editing software. Considering there are total of 128 waveforms, this can be a big work. Also, every cycle must begin and end at zero amplitude. This ensures smooth playback of each individual frame, since any amplitude difference between start and end point at such short loops alters the harmonic content or totally shifts it into wrong pitch. However, once you build it, the result can be quite impressive. In fact it is possible to gain much higher quality (longer cycle waves, more hi-fi sounding) than on a standard wavetable synthesizers. This is because a single wavetable on TS can be as big as RAM size in it. For example 1 MB wavetable contains a frame with a size of 8 kB. In the days of PPG, 8 kB was the size of the whole waveform ROM!

ts10

Some might ask how come this synth has Wavetable synthesis, yet its specs or manual don’t say anything about it – they only mention Transwaves. Well, transwaves are similar to wavetables, in many aspects identical, exept there is no interpolation calculation between to adjacent frames (waves). Single transwave is made out of 128 individual single cycle waveforms and no calculation occurs in between. In other words, what you put into is what comes out (aka garbage in – garbage out). You can’t smooth it out or change in any other way. This is what makes it different from a wavetable, along with the way the data is stored and calculated on wavetable synths. Typical stock transwave is usually made out of two major waveform frames, the first and last cycle in the transwave. However, if you have editing skills and a desire you can build any transwave you imagine, which puts this machine in the vicinity Waldorf wavetable synths and their cool wavetable banks. Unfortunately Ensoniq never provided anything remotely interesting as Waldorf’s wavetables which is probably the reason why wavetable synthesis never took off on the TS series. Kinda pity. Even the Waveboy disks and their custom wavetables aren’t much impressive (i bought them all and regretted). Still if you have patience, once you build a set of good custom transwaves, you’re in the business! And just when you though, this synth has so many cool features, we come to another chapter…

Wavesequencing – just like on the famous Korg Wavestation. Although called Hyperwave, it is basically the same thing. Offering the same methods and similar settings it has one additional and quite useful feature called crossfade volume point. As you might know, a volume loss naturally occurs in the center of a linear crossfade point and with this feature you can completely compensate it. That’s why TS produces constant volume wavesequences, making them completely undetectable – almost sounding like some kind of a morph. Of course, you can always set it to 0 dB to achieve the classic Wavestation-like wavesequence with volume loss.

Custom Transwaves (detailed procedure)
Lets now go back co custom transwaves mentioned at the beginning of the article in case you decide to put them into the TS you might encounter some problems. For example: if you want to add another layer or duplicate existing one. Once you load the sample, you can’t – for some reason. So you must do it prior to loading.Recently i found a way to transfer multi layer samples to the synth. Lets say you build few transwaves in the PC and you want to put them in TS-10 via EPS disk software. No problem, you save the sample, load it to TS and start to program it. But there is a problem. You want to add another Layer (to place the same sample there, but with different parameters for thicker sound) – TS-10 wont let you do that. So i found some really old prehistoric program called Ensoniq MIDI Disk Tools. This program requires Win98 OS, but can run on Virtual PC (Microsoft’s PC emulator for WinXP and Win7).It is a Demo version, but for some reason it will do exactly what you need (in fact, this program is for something completely different). With it, you can make a copy of existing layer and create another one (this is just a copy, so total size won’t increase!), or you can put another transwave in another layer (useful for Ensoniq Fizmo type of sounds). The trick is that this program operates directly on file. So it doesn’t matter if this is demo version, for what you need this program, will be already done even before you click exit.

Here is a procedure on how to create custom transwaves (works on ASR-10 too). This requires commercial program called Awave Studio, but if you are musician you probably already have this program as it can do 1000 other things when it comes to sample conversion:

  • First, to create a transwave use Tranzilon – nice and simple prog.
  • Then convert .wav to ensoniq .efe file via Awave Studio program.
  • Then create ASR-10 floppy with EPSDisk.exe and save this .efe file it to disk. Done!
  • In case you want multi layer, then before you use EPSDisk start that Ensoniq MIDI Disk Tools program (described above) and add 3-4 layers (or just use copy if you want the same wave, so the waveform stays in layer 1 and you don’t get unnecessary large file size). Remember, this program operates directly on file, there is no undo. So make a copy of whatever you do.

Modulation
We need something to modulate all those transwaves, wavetables, etc. right? When it comes to modulations, TS offers one good feature called: modulation mixer. This is very similar to Kurzweil equation FUN’s where you can combine two controllers, apply scale and shape to one of them and get new controller at the output. With modulation mixer you can create really incredible modulators, some of them possible only on complex modular systems. Here is more info about it (from the manual):

Here are the available shapes:

Some examples (but possibilities are endless):

A couple of my patches
Originally i had idea to build a larger demo, but instead decided to build a soundset for TS-10 first, then do the proper youtube demo. However, not to leave you empty handed i found a couple of wavesequencing atmospheric demos that i did for the legendary deepsynthesis.net web side (also known as Sealed’s Deep Synthesis for those of who still remember it!!). These are no ordinary sounds but mostly long evolving textures, demonstrating the Hyperwave function.

Regarding the soundset
I planned other demos but decided to put them in the Youtube video once the soundset is completed. Please don’t ask me when that will happen, though. It will be available on this same website. If it isn’t available then it means it hasn’t been made – plain and simple. 😉

And here is an excellent demo by thekyotoconnection that i found on a YouTube with TS-10 doing Hyperwaves and Pads. There is even a link below the video (on youtube) that provides access to the patches in that demo.

Which OS version to go for?
Stock version is in 90% cases 2.20. There has been some talk about OS3.10 being the better (latest) version, however from what I have heard one can not just swap the old EPROM chips. Some modification to the motherboard is needed. As soon as I find out what needs to be done I will publish it in here. Currently I have OS2.2. I don’t remember any specific bugs here and there, on this version of the system. Feel free to discuss below.

UPDATE: I have bought OS3.1 from here. Will have it installed next week. Fingers crossed everything goes well. I am also curious to check the sequencer MIDI jitter response after the upgrade.

Yamaha A4000/A5000 Review

a5000

When its older brother Yamaha A3000 came out in the mid 90’s it was one of the more affordable samplers on the market that featured a full synthesis engine (sampler + synth). A lot of us lusted after one, since the big E-MUs and Akais were prohibitively expensive back then, this was the second best. Still they were not cheap. In fact by the time i could afford a Yamaha A series sampler it was already year of 2002. And by the time models A4000 and A5000 were released. So i purchased one – my first real hardware sampler. It was like living a dream “wow now i finally have a sampler!”. By that time i sold my beloved XP-50 (which was my only synth) and somehow missed it. What surprised me by Yamaha was that i could easy cover all of the sounds that i liked on the good old Super JV series. The filters were full and juicy, not thin like their earlier incarnations in SY series. The machine offered a lot of different filter types as well as all the modulation routings you would require for one serious “synth style” patch. As i’ve metioned, at that time i really missed my XP-50 so first thing to do was to dig into machine and go for the basic synth patches consisting of nothing more than a raw saw or square or sine wave. Coincidently most of the patches that i’ve made there were synth style and this is exactly what i will show on this page in a form of synth demos.

You will notice that the machine sounds quite nice, yet for some reason it is quite cheap on second hand market. Well better to clear some things right away!! Read this as a warning if you plan to purchase one of these devices. Unfortunately all of the A series Yamaha samplers suffer from the same problem, rotary encoders located below main display. After some time they start to produce weird results outputting wrong values or going into wrong direction – ie you scroll down, value goes up. I should point out that i bought my A4000 brand new from the store. And after one year in smoke free studio one encoder started acting. Quick browse to the web to find out other people have the same problem. On of the cause for this might be the fan in the back the sucks the air out of the unit, which means air will be sucked in from the front side – that is from the place where encoders are, and the dust will literally be pushed into the encoder. Even if you open it up, which isn’t an easy task to clean it up, the problem might return. You might want to google Yamaha A4000 encoders and see of the solutions that people came with. Or you can buy a new set of encoders. Unfortunately this might set you back around 50 EUR which is frustrating given the unit itself can be found for less than 100 EUR.

Second warning i have to give out to potential buyer. If you plan to use this as a live unit, simply forget it. The loading times on this unit are extremely slow. Even if you load it before the concert, if power shots down for some reason you have to go thru it all again and lose a lot of precious time. Not to mention the frustration if you have several different things to load, you would have to wait several minutes in between.

Back to the features. Although called a sampler, Yamaha A-4000 offers amazing synthesis capabilities and is maybe one of the most underrated samplers. when it comes to synthesis power. For start, it gives you: 2 LFO’s, 3 EG’s, 16 different filter types with complete control over the parameters. Single patch has no layering tone limit. Many samplers had layer tone limits of one patch to contain up to four tones (waveforms) such as Akais and some Rolands. Yamaha is not limited in that way. You can stack as many tones/waveforms as you want for a single patch (well as much as polyphony allows you to). This way you can create very rich and complex sounds.

It also has some unique synthesis functions like ”expand detune / dephase” and LFO with fully programmable waveforms. Once you create new sound, you can resample it to create even more complex one. There are also 96 onboard effects inside of three (six in case of A5000) independent effect blocks, which can be connected in series, parallel or individual. Combine this capability with the resampling function and you’ll have virtually endless effect processing power at your fingertips. You can even use the A4000/A5000 as a stand alone effects processor by assigning effects to the stereo analog inputs. Here are .mp3 sound examples of Yamaha A-4000 which will demonstrate it’s synthesis capabilities. In most examples, used sample will be the saw waveform. The size of this sample is only 0.7 kB or 712 bytes to be exact!

2osc_saw_lfo.mp3 (375kB) – First we will start with standard LFO modulated filter sweep. In this case used filter was 18 dB with medium resonance applied. Sound is made of two saw oscillators octave transposed and a touch of reverb.
2osc_saw_lfo-Note.mp3 (171 kB) – Same sound, single note.
AnalogRAW.mp3 (591kB) – Analog sound made of two saw waves and one square wave filtered through band pass filter (BPF) with max width. Each osc uses random pan, square uses expand detune function.
2saw_eg_lfo.mp3 (795kB) – Another LFO sweep with two oscillators, filtered one through LPF the other through HPF, both resonant. To demonstrate effects unit, a little bit of chorus and hall efx were added.
2saw_osc+dist+delay.mp3 (273kB) – Dual saw sound, processed through TWah+OD and T-XDly efx.
2sqr_lpf18(dephase)_hpf24.mp3 (478kB) – Introducing dephase function. This will make your sound extra wide without need for efx. Two oscillators were used – both square waves. One filtered through 18 dB low pass filter (LPF), the other one trough 24 dB high pass filter (HPF). I recommend headhones for this one.
AditiveRAW.mp3 (127kB) – Remember stacking as many tones as you want on a single patch? Well this feature gives you a chance to build a primitive, but functioning additive synthesizer. Following sound was created by only using sine waveform. There are totally 8 sine waves, each controlled by it’s own LFO, but all together inside a single patch (this makes overall controlling of the patch much easier). Each sine wave’s pitch is transposed so they make standard music harmonics (second harmonic is octave up, third harmonic is 7 notes above second, fourth is 5 notes above third, etc…).
AditiveChordRAW.mp3 (115kB) – Same sound as above but a chord.
AditiveSynthesis.mp3 (310kB) – Organic type of sound created by aditive synthesis.
sqr_lfo_port.mp3 (146kB) – A little bit of fun with square wave and LFO.
expand_detune+7_singleOSC.mp3 (555kB) – The cool ”expand detune” function. According to manual this feature sets up a tuning differential (discord) between left and right channels. However, when you put the (stereo) width to 0 you get this crazy sounding PWM type of effect. Believe or not this sound example is a single saw oscilator . That is one sample, one timbre, one poly, no efx, no tricks or anything, just single saw waveform + expand detune function.
SineWave+reverb.mp3 (72kB) – Using sine wave oscillator and LFO to create simple organ. Little bit of reverb was added. Note: To create a sine wave and other ”analog” waveforms like pulse, saw, square or white noise, there are many good programs available of which some are freeware.
sqr_detune.mp3 (185kB) – Single square wave with 18 dB filter, full resonance and expand detune function set to +3.
AnalogPad.mp3 (555kB) – Following pad was created using one pulse wave, two saw waves and one sine wave. That’s all – the rest is A-4000.
SawPad.mp3 (422kB) – Another pad, this time made of three saw waves.
Resample.mp3 (137kB) – This sound started as a sine wave. Using resample, efx and a lot of programming i turned into this organ sound.
Resample2.mp3 (67kB) – Another organ sound that started as sine wave, then resampled.
transwave-mult_timbr.mp3 (2152kB) – Testing multi timbral part of A-4000. Simple drum set and a ”transwave” type of sound that i programmed.

Korg Trident MkI Demo

trident

After many years of search, and one unsuccessful purchase of a busted MkII (that i’ve never managed to repair) i’ve finally found a good condition MkI at a very good price. There was nothing to think about but to pull the trigger. Always liked that “cosmic” string sound of this machine. And in the meantime i’ve became a fan for its brass section as well, because there is something magical and retro about that brass section – it screams 70’s. Although the synth was manufactured in 1980, circuits inside were designed in the 70’s and that’s about how they sound! As of its synth section, the thyristor based VCO core can hardly disappoint you and in combination with powerful and liquid SSM filters, it just brings smile on your face each time you hit a note. Same design will be later used for the famous Korg Polysix, though many corners will be cut to make Polysix affordable for average (read: starving) musician. Trident was no doubt the flagship model, you know that big thing that dominates the center of the studio with its ability to cover a large sonic territory thanks to independent synth, string ensemble and brass sections. I just wish it had the arpeggiator and unison that later came with the Polysix. To anyone who played Polsix, already knows it is SO EASY to lose several hours just by dialing some nice resonant patch with a long release and then hitting a six note arpeggio while gently tweaking knobs. Don’t do it – you’ve been warned.

Back to Trident. While i must admit the price was good, it actually requires some minor work. Resonance does not work on the brass section (i suspect dead SSM2044), which is why brass in the demo will play only non resonant sweeps, so i apologize for that part. Also most of the push buttons are busted and these are first to be replaced after i fix the resonance issue. Luckily PCB boards inside are separated per unit, so i hope it really shouldn’t be hard to fix the brass section.

On the back of the unit there are CV inputs for synth and brass filter sections. Which is precisely what i did on one part of the demo. I’ve connected a Korg MS-20, built a simple Sample an Hold patch there and then routed that voltage into the Trident. Also used MS-20’s LFO to do the ramp down type of repeating note effects. In case you wonder how i’ve achieved that effect.

Overall the sound of the synth section is really nice, filter can be opened really high in the spectrum (not as some other analogs where it reaches certain range deep within human hearing) so you can achieve some razor sharp synth tones if required. The sound of Trident/Polysix VCO is hard to describe. It is not silky like Jupiter 8 or aggressive like Prophet 5. It is just something different on its own. I’d say somewhere in the middle between the mentioned two polys, at least for the PWM types of sounds. Bass is nice too, again unison would come as a killer feature and i’m not excluding the possibility to design it myself. I really want to hear this thing in unison because i know it will be brutal for basslines. Just like the Polysix, Trident’s VCOs don’t push a lot of power in the extreme low which is actually ideal type of VCO for unison types of sounds (you don’t end up in most of the headroom eaten by extreme low). For more info please check Robert L’s Trident review while i will proceed with the demo now:

Dynacord DRP-20 review

drp1x

German classic from the late 80’s (manufactured in 1989). For those on the other side of the great lake where this company is not so much known, we should mention that Dynacord has been a long time manufacturer for pro audio equipment. Old analogue classics like TAM-21 (flanger/chorus) and VRS-23 Vertical Reverberation System come first in mind (both from the late 70’s – still can be found relatively cheap).

Visually, what makes DRP-20 stand out in every rack is obviously its white face plate, which really looks cool. However, there is also the black face plate version around which has balanced jacks and is less noisy at the output stage (noiseless to be exact). Speaking about ease of use, i gave 5/10 because, it’s one of those devices, where you browse through the menu and tweak with the big knob. Can be time consuming and is not as “hands on” as some other devices, i.e. VRS-23 with one knob per function. Assigning patch names can be real pain in the a**, hence low mark on ease of use. I must admit everything is logically laid out in the unit, and once you get used to it, it’s point and shoot.

DRP-20 is a classic reverb processor made with a true stereo engine, which, on some algorithms can be split to “dual” mode where each line features its own “processor”. The unit features dedicated input and output level knobs with a HI/LO gain button for easy switching from a line level for synths to high gain setting for something like a guitar connected directly into the unit. On top of that, there’s a dedicated “mono input” and “mono output” jack on the front panel which guitarists might appreciate. For the classic studio setup, there are 2 inputs and 2 outputs on the back of the unit.

It is very hard to describe the sound of DRP-20 unless you actually try the unit, in your own setup, with your own gear, etc. I won’t bother describing the “sound” of reverb but rather focus on discussing the unit’s weaker and stronger points. First thing i should point out is that the short room reverb algorithms are definitely not this unit’s specialty. Much cheaper reverbs like Midiverb I and II are far better for the small rooms (ie. drums / percussion work). Luckily there are some really nice multi-taps for small room simulations to compensate for this somehow (intentional or not), but more on that later. Where DRP-20 really shines are the vast spatial reverbs. They sound so lush. And the tails on those are just magnificent! In fact i remember reading many years ago comments from ppl mistaking DRP-20 for Lexicon 480 and Quantec QRS (though this is all highly subjective, still somehow funny anecdote). One thing i know 100% sure, huge reverbs on this unit sound really really good! For some reason there are no much of them in the presets area, so you’ll have to make your own, using the buttons and the dial. Luckily there are more than enough parameters for the reverb, and every major aspect can be precisely set.

Speaking of other good stuff inside, the unit has some nice delay algorithms. One of my favorite is a VCO Delay, where LFO can be used to modulate the time. Since each line can be set independently in time and modulation amount, you can produce everything from wide choruses and flangers to old school delays with modulation (for some 60’s style Sci-Fi movie soundtrack). One very useful feature in the unit is the IN LOOP enable / disable function. Basically, when engaged, all the patches in the unit will have their “original signal amount” set to 0. In other words, all effects will be set to fully wet. This saves a lot of work to someone who’s moving from serial to loop connection or vice-versa, otherwise all the patches would manually have to be reprogrammed.

In Specs
The unit features 32 bit signal processing based around the NEC’s DSP chip. Converters are 16 bit, both the A/D and D/A section. The unit features MIDI for external control of all parameters in real time. Parameters in the unit can be set to either “value” of 0-100% or in classic dB scale which is very useful for both the beginners and the professionals – kudos to Dynacord for that. There are 128 preset locations and another 128 user locations for program storage.

DRP-20 has a total of 26 algorithms or effect structures as they call it. Each structure has its own range of parameters. Structures range from Echos, Reverbs, Plates, Rooms, Echos+Reverbs, Multitaps, Gated Reverbs to the Flanger and Chorus effect. There are also five dual channel algorithms which basically feature echo line on one channel and room or plate on the other channel.

Speaking of Multitaps, last algorithm features 2×11 taps which can produce some really nice room simulations! Those 11 delays per channel are grouped with another channel to form a stereo cluster which can be drawn using cluster time function. It is possible to select one from 9 different clusters for each channel, for some really exotic stereo room effects. Further more, cluster time can be independently set for each channel (L & R) along with the independent feedback amount for each. With some careful programming, a collection of really cool room reverbs can easily be built.
