TherapSID mk 3 Synth Module SN TS322010

via this eBay listing

"The TherapSID mk III is the final and best version of an awesome synth module built around the Commodore 64 SID chip. This one features an original 6581 SID chip pulled from a broken C64 (although the module can also host new SID emulator chips).

To quote the manufacturer: 'Named after a vicious dinosaur, its sound is no less aggressive. TherapSID has evolved to create roaring noises that will cut through your mix like razor-sharp claws through a mammoth steak.'

TherapSID unlocks the power of the SID's 3 oscillators plus noise and multimode LP/BP/BR/HP filter and adds 3 envelopes, 3 LFOs, a fantastic arpeggiator, 3 CV inputs, and much more! It can run up to two SID chips at once, with audio inputs and outputs for each chip. This unit is running firmware version 2.6, but other versions can be installed over MIDI."

1985 Sequential Multi-Trak 61-Key 6-Voice Polyphonic Synthesizer SN 00080

Additional SYNTH CITY Listings

"The Sequential Multitrak (released in 1985) is a six-voice analog synthesizer notable for combining true analog sound with early digital control.

Each voice has a CEM3394 synth-on-a-chip, offering a single oscillator, sub-oscillator, noise source, and resonant low-pass filter. It was one of the first affordable synths to feature a built-in sequencer and MIDI implementation, making it popular for both studio and live use.

The Multitrak’s panel and parameter editing system allowed deep sound design, though programming could be a bit tedious. Its warm, punchy tone and distinctive Sequential character make it a cult favorite among vintage synth enthusiasts today.

This one works like a charm and has that analog warmth you've been looking for in a polysynth. One button has been replaced on the "to tape" cassette loading feature. Includes original power supply."

"Original SCI Pro-One with MTG Turbo MIDI kit installed!

Cosmetically, it's seen better days, but sonically - it works. Has been stored for two years and some key contacts needed playing after that time. It's time for a new home where it's appreciated!

The instrument was serviced in 2023 by the legendary Greg Montalbano of Analog Synth Service in Oakland.

Cleaned, tuned & scaled. Assessment: MTG MIDI unit works, but the CV option was incorrectly soldered, and the DAC for the optional CVs doesn't work. Upgraded fixed power cord to removable IEC power socket"

M-Audio Venom Purple Beta Tester Version

"M-Audio Venom Purple Beta Tester Version As far as I know there was only one other of these made in this color. [only two other listings were previously posted here. You'll also find a post on Venom creator Taiho Yamahda's blog. Taiho is now with Sequential.] The production units where white with orange and black lettering. I was one of the beta testers and sound programmers for this synth. Since this was a beta tester model the Midi was not fully functional when I received it. We did all of updates thru the USB however so don't know for sure if there was a change to the hardware or it just needs a firmware upgrade. Was just going to buy another production model and swap out the motherboard but never got around to it. It has all of my factory program contributions in bank C. 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."

Cwejman S1 MK2 Semi-Modular Monophonic Analog Synthesizer w/ Original Box

via this Reverb listing

"MINT CONDITION (see images), AS IF YOU RECEIVED IT FROM THE SHOP IN 2019!

This is the legendary Cwejman S1 MK II synthesizer, unused in box. I received this in 2019 after ordering ist sometime mid 2010s ... and due to different life circumstances never used it as when I received it I just had moved and no space for my Eurorack system.

As a result, this unique synthesizer is like a time capsule, it was safely stored in my office in its original packaging in a cupboard and is in mint condition (refer to images)."
