Synton rare vintage synth modules -VCO/LFO/VCF/ENV
via this auction
"Here are a collection of rare Synton Modular Synth modules.
There are untested ,and do not come with a power supply and theVCF has had its pots de-soldered to fit in another system.They run on a standard +/-15v supply and have all the original knobs and banana connectors .All of the modules have their power connections on bare wires.Due to their age and because I can't test them , they are sold as seen for spares or repairs.They were bought by me as a project to repair , but I don't have the time and they should go to a better home.There are no returns.
The modules include :
3021 VCO with CEM 3340 VCO chip , it has a variable square wave , sawtooth and sine wave output all available at the same time.sync and PWM and Linear FM inputs.This module was working fully , but is now untested.
3023 VC LFO /VCO - triangle , square outputs , voltage control in of frequency and a variable waveform that goes from sawtooth to triangle to inverted sawtooth
3235 ENV/CPR - this is an envelope follower, trigger delay , and CPR , which is I think a trigger that is generated when a voltage is input above or below a variable set voltage level.
3010 VCEGR - this is a voltage controlled Envelope generator with every stage of the envelope controllable by CV for very expressive and complex envelopes.Standard gate input and VC input for ADSR.
3047 VCF - a multi-mode VCF , which is variable from low pass to hi pass through notch on a variable knob.frequency and resonance controls and a separate band pass output.This is a really nice and unusual filter.Does not use a CEM or SSM chip, so sounds very different.This one has had the pots and banana's de-soldered presumably to fit into another format , but it's easily put back together- nothing is missing.
The modules come with a eurorack format case that is solid and heavy , so if you are just interested in the modules , you don't have to have the case.The modules are not fixed in , but were put in this case for safe keeping.
Synton modules are extremely rare and were very high quality , these have not been tested recently , though they were working with a +/- 15v power supply in the past.These are sold as seen ."
Splitloop Roland TB 303 Bassline Synth with CV/GATE Mod
via this auction
via the listing:
"It comes with a VERY handy CV/GATE IN mod, which you can use to control the 303 from your sequencer if you have a MIDI>CV convertor...I use a Novation BassStation to do this, but a lot of the time I just use the onboard sequencer anyway."
"I'm finally letting my piece of Dance Music History go! If you've found this item you know exactly what this is, it's a hell of a lot more than the sum of it's parts. This thing is an animal, which I've used on many many tracks..."

Concertmate-200 Keyboard Synthesizer - Casio VL-1
via this auction
"This nice Realistic C-200 Keyboard is actually a Casio VL-Tone 1 clone specifically built for Radio Shack stores!
The Concertmate-200 is a monophonic VL-Tone 1 (VL-1) synthesizer with built-in calculator. The "M+" calculator memory also stores the timbre, ADSR, vibrato and tremolo setting for the synthesizer, and the short 29 buttons mini- keyboard could be transposed by a switch to low, mid and high pitch range. (In Germany the VL-1 became very famous by the pop group Trio's song "Da Da Da", which features the "rock" rhythm and piano sound of this tiny white keyboard.) The VL-1 was the first genuine "Volks- Synthesizer" and came out even earlier than the well known Yamaha DX-7. It was first released as the Casio VL-Tone 1, and later as the Realistic Concertmate-200.
Overview
29 Button Micro-Keys
Monophonic Main Voice
5 Preset Sounds : piano, fantasy, violin, flute, guitar (selected by slide switch with a small delay)

24 Preset Patterns (8 Drum Rhythms / 8 Accompaniments / 8 Funny Arrangements)
Volume Slider Control

3 Octave Transpose Switch
Full-Function Built-in Calculator
ADSR synthesizer (uses calculator memory as sound parameter register)

Special Note
The Realistic C-200 Portable Electronic Keyboard is part of the Casio VL-Tone 1 synthesis series.
The C-200 is a monophonic sound generator based on multi-pulse square-wave tones with different digital envelopes. The digital envelopes with audible zipper noise are linear, and the analog rhythms consist of 3 (high, low, snare) sounds made from square-wave and shift register noise.
The C-200 Synthesizer has a fun variety of fantastic voice tones to modify and drum rhythms to play to."
