"The elephant in the room: Roland JP-8000, Clavia Nord Lead A1, and Access Virus B: Three legendary hardware synths from the late 90s/2000s that still hold up today. But which one is worth your money in 2026?
In this video, I go hands-on with all three machines from my studio, playing patches, presets, and sounds I programmed myself. No script, no BS — just honest thoughts after owning these synths for up to 21 years.
What you'll learn: JP-8000: SuperSaw magic, but what are the real limitations of the filter? Nord Lead A1: Why it's my go-to synth — and why the Moog filter is a game changer Access Virus B: The all-in-one machine with 24-voice polyphony... and where it hits a wall Should you buy hardware or use emulations? (honest take)
These are timeless machines. This knowledge will be valid in 10 or 20 years. Maybe some plugins won't exist by then — but these synths will.

"The Mask1EX desktop synthesizer is back, with new looks and new features! Mask1EX MK2 offers 14-voice polyphony with two Bitmask oscillators for each voice - Bitmask Synthesis is exclusive to all Kodamo's Mask synthesizers, it produces a wide range of unique tones by using a single number as parameter. Mask1EX MK2 also has built-in effects, a looper, an arpeggiator and much more."
"It is back, with a totally new design, more powerful than ever! The Mask1EX is a desktop synthesizer that you can use with your keyboard, DAW, sequencer or any other gear with MIDI. Like other Mask synths, it is based on our exclusive Bitmask synthesis technology which generates up to 512 different waveforms for oscillators. It offers 14-voice polyphony with two Bitmask oscillators per voice and 2x2 parts of multi-timbrality (two parts of single or dual layered voices). Each part comes with stereo effects to make the sound warm and rich, plus a master effect with delays and reverbs.
Like the Mask1 keyboard, the Mask1EX MK2 offers an incredible playing experience with its dynamic articulation system. Try the slurred, poly-mono and hybrid modes, they add a new dimension to keyboard playing, changing how the sound behaves as you play legato, staccato, neighbor notes or wider intervals.
Mask1EX MK2 is powered by USB-C and is extremely efficient with 1.5W of power consumption, which makes it easy to power by a battery, laptop or smartphone. USB supports class-compliant Audio and MIDI. We also included good old DIN MIDI ports for compatibility.

"This collection of vintage synthesizers has grown with me for years. Most all of these instruments have been used on many projects, including VeggieTales, a variety of remixes, and many PlayStation video games and marketing and promotional discs. Most recently they were used on the Mass Effect Andromeda video games soundtrack. They have also been sampled and are part of the SoundVault Collection and the Kurzweil Analog Collection for the K2000 series samplers. VEMIA note: to forestall many inquiries, The seller’s idea is that he wants to sell it as a whole. That may or may not work out in this auction. If it doesn’t, obviously he’ll be free to do whatever he wants after the auction finishes.
It all works. Everything has been kept in a clean, smoke-free, climate-controlled studio. I have always fixed things myself, so everything is operational and sounding great. I have repair notes on the synths that received attention, though most of them have worked great over the years, without much need for repairs. There are also several MIDI to CV converters so they can all be controlled by computer, plus cables if desired. And a few have cases and manuals.

A desktop spring reverb unit featuring a built-in miniature spring.
You can use its high-quality, authentic spring to achieve a beautiful, classic reverb—or you can dive headfirst into the lush, vibrant resonance of a wildly oscillating spring, letting yourself drift and drown in its saturated wetness. It gets absolutely drenched.
And while nobody explicitly told you to shake it, smack it around, or slam it against the table... well, naturally, you’re going to do it. After all, there’s a real spring inside that actually shakes! It’s the thrill of the authentic.
Mix the clean-boosted signal (GAIN) with the spring-reverb-processed signal (REVERB), then adjust the overall output volume using the LEVEL control.
When the switch is in the down position, the signal bypasses the effect, passing directly from IN to OUT. The LED illuminates when the effect is active.

39C3 - From Silicon to Darude Sand-storm: breaking famous synthesizer DSPs
Have you ever wondered how the chips and algorithms that made all those electronic music hits work? Us too!
At The Usual Suspects we create open source emulations of famous music hardware, synthesizers and effect units. After releasing some emulations of devices around the Motorola 563xx DSP chip, we made further steps into reverse engineering custom silicon chips to achieve what no one has done before: a real low-level emulation of the JP-8000. This famous synthesizer featured a special "SuperSaw" oscillator algorithm, which defined an entire generation of electronic and trance music. The main obstacle was emulating the 4 custom DSP chips the device used, which ran software written with a completely undocumented instruction set. In this talk I will go through the story of how we overcame that obstacle, using a mixture of automated silicon reverse engineering, probing the chip with an Arduino, statistical analysis of the opcodes and fuzzing. Finally, I will talk about how we made the emulator run in real-time using JIT, and what we found by looking at the SuperSaw code.
This talk is a sequel to my last year's talk Proprietary silicon ICs and dubious marketing claims? Let's fight those with a microscope!", where I showed how I reverse engineered a pretty old device (1986) by looking at microscope silicon pics alone, with manual tracing and some custom tools. Back then I claimed that taking a look at a more modern device would be way more challenging, due to the increased complexity.
This time, in fact, I've reverse engineered a much modern chip: the custom Roland/Toshiba TC170C140 ESP chip (1995). Completing this task required a different approach, as doing it manually would have required too much time. We used a guided automated approach that combines clever microscopy with computer vision to automatically classify standard cells in the chip, saving us most of the manual work.
The biggest win though came from directly probing the chip: by exploiting test routines and sending random data to the chip we figured out how the internal registers worked, slowly giving us insights about the encoding of the chip ISA. By combining those two approaches we managed to create a bit-accurate emulator, that also is able to run in real-time using JIT.
In this talk I want to cover the following topics:
What I learned since my previous talk by looking at more complicated chips
Towards automating the silicon reverse engineering process
How to find and exploit test modes to understand how stuff works
How we tricked the chips into spilling its own secrets
How the ESP chip works, compared to existing DSP chips
How the SuperSaw oscillator turned out to work
[Note: although DiscoDSP gives credit to The Usual Suspects, it's my understanding TUS is not happy about it. From a forum:
"He basically took our source, put his own wrapper on it and is trying to sell it and use it to promote his own business. Can't prevent it, but frankly this is reprehensible IMHO.
Yes. He knows he cannot legally "sell" it due to the licensing model our code is published under. Therefore he sells "support" of "his development efforts" to include difficult things like "git clone" and other Arcane and extremely difficult stuff. sigh... I'd strongly advise anyone using it not to actually pay him for it, but that is just my opinion.]
What isn't clear is whether the UI is just the player above or includes the full editors by The Usual Suspects. I'm hearing it's just the player, which in effect might be an upsell for the full editors by The Usual Suspects.

"Retromulator brings legendary hardware cores back to life through authentic low-level emulation. The virtual analog synths are powered by a faithful recreation of the Motorola DSP 56300 processor, the Yamaha DX7 runs a full emulation of its original chip set, and the Akai S1000 sampler plays your SF2, SFZ, and Bliss sample banks with studio-quality interpolation. Each core runs its actual firmware or sample data — delivering the unmistakable character of hardware that defined electronic music from the early 80s through the 2000s.
Unlike traditional software emulations that recreate synthesizer behavior by approximation, Retromulator emulates the original integrated circuits at the hardware level. The virtual analog synths run on a cycle-accurate Motorola DSP 56300, the Yamaha DX7 runs a full emulation of its Hitachi HD6303R sub-CPU and Yamaha YM21280/YM21290 EGS/OPS chip set, and the Akai S1000 sampler runs on the SFZero v3.0.0 engine with 8-point sinc interpolation supporting SF2, SFZ, ZBP, and ZBB sample banks. Each core executes its authentic firmware or sample data exactly as intended.
Load the ROM firmware from your own hardware or sample banks from your library, place them in the designated folder, and Retromulator takes care of the rest. The result is not an approximation — it is the real hardware running inside your DAW.
Retromulator is built on Gearmulator, an open-source synthesizer emulation project by the dsp56300 team. We are grateful for their extraordinary work in bringing these classic instruments back to life."
"VA-1000 is a 16-voice virtual-analog synth built for speed: JP-style Ultrasaw, deep unison, a 9-mode filter with audio-rate LP FM 12, expressive LFOs and three envelopes, plus chorus / delay / reverb with ducking, all on a clean one-page UI. Software Download (NO HARDWARE INCLUDED)"
"It took some time to master the workflow of the @SONICWARE ELZ_1 Play synth, but it was absolutely worth it. The size is small, but the sound is big, and I couldn’t have had a better way to ride out the snowstorm this weekend.
Big shoutout to folks like @ChrisLodyMusic and @nicafelt whose videos and guides make the learning curve much easier, on top of Sonicware’s own excellent documentation.
In this video, I demonstrate the Trance Leads from the True Trance V1 soundset. These presets & patches work with the Roland JP-8000/8080, the Usual Suspects JE-8086, and other compatible synthesizers that support this format.
This overview features:
4 my original trance melodies from 2007-2009 years
Authentic 90s lead textures
High-gain Supersaw sounds
Real-time synthesis demonstration
I showcase how these sounds perform across different compatible engines to recreate the iconic golden era of trance. Each lead provides the clarity and power required for professional productions. All audio examples in this demo highlight the versatility of the soundset.
