"In excellent condition, only used in a pet-free and smoke-free home studio. Apart from a small dent (see photo), no external or internal flaws.
It has been improved by famous Moog tech Rudi Linhard, i.e. memory upgrade (1024 presets), slew rate mod, aftertouch mod, and panel backlight modification - the original Anniversary Edition machines had a problem with an audible whine from the (otherwise beautiful and extremely useful) panel backlight. Rudi has re-calibrated this so that it is only noticeable when the backlight is turned to maximum.
This lovely synth is available for collection from Nuremberg, or VEMIA can organise collection / packing / delivery at cost."

"The Roland Super JX (MKS-70 / JX-10) is one of Roland’s most underrated analogue polysynths. Released in 1986, it was effectively two JX-8P synth engines in one instrument, giving you 12 voices of DCO analogue synthesis, huge pads, powerful basses, and classic mid-80s Roland character.
In this video I take a deep dive into the Roland MKS-70 Super Jupiter rack synth, paired with the Retroaktiv MPG-7X programmer and the Vecoven PWM upgrade, which massively expands the capabilities of the original synth.
We explore how the controller transforms the experience compared with the original menu-driven interface, and look at the additional synthesis power introduced by the Vecoven upgrade including true PWM, additional envelopes, extra LFO, and expanded modulation routing.
Along the way I demonstrate a range of sounds including pads, basses, evolving textures and layered patches, showing why the Super JX became famous for its huge analogue pads and rich detuned sounds.
I also look at some of the performance features of the MPG-7X such as assignable controls, patch generation, chord mode, velocity crossfading and MIDI integration, which make this combination feel like a modern analogue synthesizer despite the vintage hardware.
If you're into vintage Roland synths, analogue polysynths, or classic 80s synthesis, the Super JX is a fascinating instrument sitting right at the transition between the analogue era and the rise of digital synths like the DX7.

"Exploring the legendary VCFQ filter in stereo!! It's a perfect filter to pair with the medusa. I hope you enjoy listening to these patches as much as I enjoyed making them.
There are some jams at the end if you want to hear more musical applications with the filter. A few pinging sections of course, some pads, ambient, industrial and synth wavey goodness.
Lots to explore with this versatile filter, now made better in Stereo!"
"For this * very long * 'one synth only' jam, you'll be able to hear the sound of the Perfourmer with and without the effects pedals 😉 (and even with and without the MIDI effects of the Hapax sequencing the Perfourmer).
The Perfourmer is setup like 3 instruments here:
Voices 1&2 for the PLUCKS thru the H90 pedal
Voice 3 for the LEAD/PADS thru the Lofi Junky + Bigsky + Pill pedals
Voice 4 for the BASS thru the Apocalypse + Julianna effects
The Perfourmer is fully sequenced by different tracks of the Hapax."

In this piece, sound is not simply performed — it is discovered, shaped, and gently guided through shifting layers of time.
'forwards and backwards in time' is an ambient improvisation created with the Polygene II by Gene Synths.
The instrument itself feels less like a machine and more like a crafted artifact — a delicate fusion of art and sound design. Its finely detailed structure, almost ornamental in nature, reflects the sonic worlds it reveals: intricate, fragile, and deeply expressive.
Textures emerge like fragments of a submerged civilization, or like transmissions from a distant future. Each movement carries a sense of both memory and anticipation, as if the sound exists outside of linear time.
This improvisation embraces that ambiguity. There is no fixed destination — only evolving patterns, subtle shifts, and moments that appear, dissolve, and reappear in altered form. The Polygene II becomes a medium rather than a tool, allowing intuition to lead the process.
What unfolds is a quiet exploration of atmosphere and detail — a space where sound feels suspended, moving simultaneously forwards and backwards in time.

"A macOS MIDI sequencer that is simply fun to use—featuring the playful motion of a bouncing ball. It is currently available for purchase on Payhip.
・Simple ・Highly expressive ・Fun to use These three principles form the core of its design. While I do plan to add more features in the future, I intend to remain steadfast in upholding these three fundamental pillars. DAWs like Ableton Live consolidate almost every conceivable function into a single package, allowing you to do just about anything; I rely on them heavily myself. However, isn't there also a unique joy in treating individual applications on your computer as distinct modules—combining them in various ways to create something new? This very concept is why I chose to handle MIDI directly rather than developing this as a standard plugin. And, of course, sending MIDI signals out to trigger external hardware instruments is a delight in its own right! I have intentionally designed the interface to avoid the need for precise note-by-note (Do-Re-Mi) input via a traditional piano roll. Instead, I encourage you to experiment with different keys and scales to find the perfect musical balance that feels right to you. My hope is that you will feel free to create and play sounds in a way that feels natural and accessible. But why the bouncing ball? Aren't you a little tired of watching static step sequencers or piano rolls scroll endlessly across the screen? I felt that the dynamic motion of a bouncing ball had a wonderful synergy with musical rhythm and beat. Plus—let's be honest—it just looks adorable as it bounces along!"
"AstroLab is less a synth and more an idea machine—a source of instant inspiration, perfect for grabbing a sound and running with it. The lack of deep editing is a trade-off for speed and variety. If you’re the type who wants to modulate an LFO with another LFO, look elsewhere. But if you want to make music now and worry about the details later, the AstroLab 37 is a serious contender. As always, the real magic—and a few quirks—are best experienced., let the jams and sound demos do the talking."
"Yeah, I FHIXXED IT. I own a VHIKK X. I had to have one, and waited for it for six months. But I completely overlooked the powerhouse I had lying around, gathering dust. Laniakea is a relatively cheap 220 euro module, and I guess - not sure - many of you have an Oneiroi - or an eye on it. If you'd combine those two, you'd open a SuperCluster and sometimes it will make the VHIKK X blush. Again, this proves for me that the best sounds you can imagine may already be hiding in the gear you already own. Next time you hear a 'must have', you may already have it."
