Kawai K3 PolySynth

via this eBay listing
"The K3 is a six-voice wavetable synthesizer with 32 waveforms, some of which are unique waves and others are samples of acoustic instruments like piano and percussion. Each voice consists of two digital oscillators run through an analog filter (based on SSM2044 filter chips), and an analog VCA. The sound of the K3 is reminiscent of the PPG Wave 2, 2.2 or 2.3, and it can produce deep, lush analog/digital sounds. The K3 is ergonomically like other mid-80s synthesizers, with membrane buttons and an encoder for editing parameters. This cost effective classic synth is a perfect addition to any player who craves something different!"

Studio Electronics MidiMini 3 OSC MonoSynth SN 1304

via this eBay listing
"The Midimini was Studio Electronics' first series of synthesizers built from scratch. Prior to the Midimini was the Midimoog, which consisted of actual Minimoog circuit boards retrofitted into a rackmount enclosure. The Midimini does not use the original Moog circuit boards, but instead Studio Electronics designed their own boards. Minimoog users will find the layout to be quite familiar with some nice additions such as a dedicated modulation LFO, oscillator sync and switches for aftertouch control. This unit is in very good condition with a bit of rack rash on the top and bottom. If you are looking for that classic MiniMoog tone, wicked huge basses and leads.. This box delivers!"

"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
Note: links to listings are affiliate links for which the site may be compensated.
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).
0:00 Introduction
0:10 Patch I: entropic
3:28 Patch II: ecologic
