"This ARP Pro-DGX is a thirty preset monophonic analog synth with digital controls. The 37-note keybed has aftertouch for volume, brilliance, vibrato, wow, growl, and bend effects - and even all at once if you desire! A few basic filter, envelope and LFO controls allow some tweaking of the preset sounds. Get your classic Tony Banks sounds with this unique Arp - no other synth sounds quite like it."

ARP Odyssey Mk II 2813 with Sub-Oscillator Kit Installed SN 1157

via this eBay listing
"The Odyssey was Arp's competition to the Minimoog in the 1970s. It is a 37-note two-oscillator analog synth, and it has a duophonic keyboard, meaning that you can play two notes at once (for which the Odyssey assigns one oscillator to each note). This Odyssey also has our Sub-Oscillator Kit installed which gives it square-wave sub-oscillators for each of the Odyssey's VCOs, and a control potentiometer for mixing in the amount of each sub. The resulting sound is monstrous!
This Odyssey is a Mk II model 2813 and it is in good condition. It was serviced by our technicians and is ready for many more years of use. It really is a perfect addition to any stage or studio."

FREE SYNTH: XENIA (Waldorf Microwave II/XT Emulator) - No talking demo
video upload by ADL-MusicLab
"Hello, everyone!
Here's to you my 'No talking demo' of the amazing XENIA, a FREE software emulation of the Waldorf Microwave II/XT by 'The Usual Suspects', which brings back to life these iconic synthesizers!
'The Usual Suspects' is a group of people who are currently Reverse Engineering and Emulating the DSP chip from original historic hardware synthesizers, which, in this case, is the Motorola DSP56300.
As is usual with The Usual Suspects releases, you’ll need to provide the original ROM, legally acquired, of course.
The architecture, signal flow, and character closely follow the original hardware, making this an absolutely faithful Waldorf Microwave II/XT recreation in software form.
More info here:
https://dsp56300.wordpress.com/xenia/
In this demo I will just let you hear what some amazing sound designers have made for this stunning plugin simply by scrolling and playing some beautiful sounds."
1/16/26 (first patch) Lorre Mill Double Knot v2 + Roland RE-301 + Alesis MIDIVERB II + CXM 1978
video upload by Cfpp0
"We just got this used. It’s heavier than expected, and the recycled plastic surface has a nice texture. With no labels or logos it will take some time to memorize how to operate it, but here’s a first attempt—some quasi-Buchla based on the quick-start patch in the manual. The Double Knot is panned center, with a reversed reverb from the Alesis MIDIVERB II panned a bit right, the Roland RE-301 tape echo panned a bit left, and a stereo reverb on all of them from the CXM 1978."
Ecodynamics: generative music from ecological processes (2 patches)

"Introducing 'Ecodynamics' – a Lua script for Disting NT, coded with Claude. This project grew out of my interest in minimalist processes, “controlled probability,” and “biomodelling” (using modular synthesis to mimic natural processes).

RORSCHACH -TV drone jam
video upload by DecadeBridge
RORSCHACH is a video synth with "an audio output that converts the video signal into a distinctive drone voice." Full details below.
Video desciption:
"All audio from Rorschach running through a cheap delay pedal. The vertical movement on the screen is due to the faulty tracking on the TV. All patterns generated by Rorschach.
10% off pre-order.
Rorschach is available from the following places:-

Rorschach by Lumatic Visual Devices is an analog-style video synthesizer designed for artists exploring video synthesis, live visuals, and audio-reactive image generation. It works equally well as an entry point into video synth hardware or as a creative expansion for experienced users.
Rorschach is well suited to live performance, with the ability to self-generate evolving patterns using its built-in randomisation features. Its functionality can be extended further by feeding control voltage, gate signals, or audio into the modulation inputs, making it easy to integrate into modular and experimental setups.
With a clear, functional, and immediate control layout, Rorschach is an excellent starting point for anyone taking their first steps into video synthesis, while still offering enough depth to remain engaging for more experienced users. Compact and portable, it also features an audio output that converts the video signal into a distinctive drone voice.
Rorschach generates its own black and white composite video patterns straight out of the box. Its functionality expands further when used alongside modular or Eurorack systems, or when audio signals or control voltage are fed into the CV and gate inputs. The focus is on experimentation, play, and hands-on control.
A dedicated random section allows the synthesizer to run freely, generating evolving patterns automatically and in real time. Leave it running during a performance, or introduce external signals such as a kick drum or sequencer to push the visuals into new territory.
Key features
Four main controls for horizontal position, vertical position, width, and height
– CV inputs for all four parameters
Form control selects from six pattern generator modes
– Can also be modulated via audio input or control voltage
Random control sets the amount of randomness applied to the four position parameters on each refresh
– Independent switches and gate inputs for each random parameter
– CV input for random amount
Clear screen modes:
– Clear / Random Clear / No Clear
– Gate input for clear screen
Pattern colour switching:
– White / Black / Invert
Horizontal and vertical mirroring switches
– Independent gate input for each axis
Composite video output via RCA connector
Audio output allowing the generated visuals to be used as a drone sound source
Power Rorschach is supplied with a 9V battery clip.
If you would like to run Rorschach off a wall adapter you will need a 9V CENTRE POSITIVE adapter.
Power requirements:- Minimum 70mA
ELEKTRON Model Samples - ENCODER REPAIR!
video upload by ST Modular (Stefan)
"My Elektron Model:Samples encoder started to move slowly and skip values.😵💫
So I reached out to Elektron, and they were incredibly supportive and sent me two replacement encoders 🙌
After the repair, everything works perfectly again! It honestly feels like a brand-new machine! ✨
