"M-Audio Venom Purple Beta Tester Version As far as I know there where only a few of these made in this color. The production units where white with orange and black lettering. I was one of the beta testers and sound programmers for this synth. I upgraded the motherboard recently to a production release motherboard swapping out the beta motherboard. When I swapped the motherboard I reset it back to the factory patches but will provide a download of my patches that I programmed during the development of this synth. I also put in a new old stock keybed as the original one had yellowed, the new one is a bright white. While it requires using the editor from either a Mac or PC to program it completely it has a broad range of possible sounds. It is a very fat sounding synth."

10 step Sequencer - Monotron/drone/pedal by Psychiceyeclix

video upload by Psychiceyeclix
"10 step sequencer, controlling cutoff on monotron, speed on pedal, oscillator on drone."
via this Reverb listing
"This 5v sequencer was bought new and lightly used in my smoke free studio. It's in full working order and excellent condition. Has a 1/4 CV output and comes with a 5v power supply.
Different combinations of steps can be made by switching steps on and adjusting the knobs. They all affect each other so there are random results in the outputted sequence. Starve knob - slowly turn knob until effects are heard in the sequence. Hold button will stop sequence whilst pressed."

"Super rare British analogue monosynth from Clef Electronic Music. Recently serviced and working well. Classic late-70s/early-80s panel with hands-on control: dual VCO section (with glide and sub-octs), noise, LFO, ADSR, and a great-sounding VCF with resonance. Compact keys, wood-effect cheeks and that gloriously utilitarian UK boutique vibe. Great for leads, SFX and modulated drones. Hard-wired UK mains cable fitted (240V).
Rear panel has Line Out, Headphones, and Speaker jacks. There’s also a “Sequencer” connector/jack present on the back panel; interestingly, this unit (and others we’ve seen) were built with no internal sequencer circuitry fitted, so the connector is effectively a vestigial feature."

video upload by Tweeeeeak!
"Introducing ROAT v2 Oscillator for Korg Nutekt NTS-1, adding FM, External Audio Processing, Chromatic play and Chaos for sequemces.
This Oscillator is free. Download link:
https://github.com/tweeeeeak/nts/blob...
(Follow me on X: https://x.com/tweeeeeak)
ROAT is an 8-bit experimental oscillator inspired by the Soma "Rumble of Ancient Times" synthesizer.
It includes 4 oscillators that can be triggered independently, by pressing 4 different zones of the keyboard, or recording a step sequence.
Combining oscillator activation with the different settings per oscillator (pitch, shape, LFO) and different combination algorithms, and adding randomization and chaos, gives you a wide range of sonic possibilities, from melodic to digital noise.
Settings per oscillator:
Pitch
16 different waveshapes
LFO (for pitch or amplitude) with 8 different shapes
16-step rhythmic sequence, syncable with external devices
Additional features:
3 oscillator combination diagrams with 7 different summing algorithms per node (including FM)
2 randomization algorithms
External audio processing (NTS-1 mk II only)
Chromatic play"
LinnStrument 200 Bumpy Surface
video upload by Sound Workshop
"our Bumpy #LinnStrument Surface makes it easier to play by feel instead of by sight. We’ve shipped over 150 surfaces for LinnStrument 128, and preorders are now open for LinnStrumenf 200. Shipping in Feb 2026. Order before Dec 8 for a 15% discount.

"One BLACK aftermarket silicone surface for LinnStrument 128. LinnStrument not included.
This surface makes it easier to play LinnStrument by feel instead of by sight. Each row is shaped like a long speedbump, which has three benefits:
Guides fingers to stay on target during long pitch slides
Provides confident tactile feedback when shifting a finger up/down between rows or hitting a double stop
Allows more intentional Y expression by feeling for the front, back, or crest of the bump
The grooves are centered over the top of the notes, instead of on the boundaries. The way the finger can feel when it's on target.
The root note bumps or dots have been removed to make alternate tunings easier.
This surface is great for playing LinnStrument with eyes closed or playing with two hands.
International Customers: prices listed do not include import taxes or fees. Please note that you may need to pay an additional custom when importing.
Black Surface Back Side Cosmetic Issue (Oct 22, 2025): the remaining 8 black surfaces have unintended paint application on the back side. After installation this is not visible to the user, and it has no functional impact. Some examples are shown here. We apologize for the suboptimal appearance. The price has been reduced %10 for the remaining stock. Thank you."
