Korg PS3100 & SQ10

YouTube Published on May 18, 2012 by noddyspuncture

"Here is my PS3100 being sequenced by my SQ10. It is a six note sequence which turns into simple 're-triggering' when I turn up the portamento on the SQ10... which is where I play the chords, to add some melody. The PS3100/SQ10 combination seems pretty versatile even though the SQ was intended for the MS range. No 'CV in' on the PS though but there are ways around that...;c)"

Korg PS3100 - Squarewave Mod - Rhythmic VCA

YouTube Published on May 5, 2012 by noddyspuncture

"Another of my PS3100 videos. On this one I am modulating both Osc, Filter and the VCA with ModGen1 with a square wave and set to a slow speed. Playing on the down stroke as it were, you just get 'blips'. Some cool rhythms can be coaxed out of her this way...;c)"

"A General Overview of the Korg PS3100 Polyphonic Synthesizer.Only 300 of these synthesizers were produced by Korg in 1977. This video is my humble attempt to share the unique layout of this rare synthesizer. I only wish I had more time to delve deeper into this synthesizer.Apologies in advance for any informational inaccuracies. Audio demos to follow. Sound and Video by Raul Pena. Special Thanks to Switched On Electronics in Austin,TX for providing the sampling time to make this production. For another take on the Korg PS3100 check out Automatic Gainsay's Korg PS3100 Videos."

Korg PS3100 - Squarewave Modulating Osc, Filter & VCA

YouTube Published on May 7, 2012 by noddyspuncture

"This time I also have full depth modulation on the VCA. You just get a 'blip' playing on the up beat, when the square also happens to be lowest ~ VCA closed. Get it right and you can get some interesting rhythms going..!"

PS3100 triple vactrol resonator for Eurorack DIY

Published on Mar 17, 2015 fonitronik

"A short demo of the PS3100 resonators for Eurorack. The module features three vactrol based voltage controlled bandpass filters with fixed Q, as known from the PS3100. It provides a common input and output for all three channels, as well as single in- and outputs. The on-board wide range triangle LFO is resettable (sync) and is normalled to the CV inputs of the 3 BPFs. The LFOs signal can be inverted for the 3rd channel."

Korg PS3100 Abstract drone1

Published on Jan 2, 2016 Peter Maas

"Drone created with the Korg PS3100 analoge, semi-modular polyphonic synthesizer. Very small amount of delay added. It's surely not the only thing the PS3100 is good add, but for sure one of its' main strengths!"

Korg Professional Laboratory Systems

Click here for a full sized image of the ad to the left on Korg Kornukopia. The ad is for the Korg PS3100 and PS3300 fully polyphonic analog modulars. Yep, fully polyphonic. Each offered full polyphony at a stagering 48 voices - you could press every key down and they would all play. They used divide down circuitry for the oscillators but each note triggered its own dynamic filter, envelope and VCA. The PS3100 featured 32 patch points and the PS3300 featured over 60. The PS3300 was in essence three PS3100s in one.

Update: I shouldn't have to say this but for high priced items like this do your due diligence. Someone reported this seller attempted to sell a fake Buchla module on Muffs (you can find a thread on it here). That said, I have no way to verify it, and I have no idea it this is just coming from someone that has an issue with this seller, or wants to buy it and is attempting to distract other buyers, or other. As always, do your due diligence.

"This Vintage Korg PS3100 PS-3100 Patchable Fully Polyphonic Synthesizer looks like it just came fresh off of the assembly line in Tokyo.

This is the one that you've been waiting for. Collector/museum curator alert.

This synth came to us in 'closet classic' condition, with hardly any wear from a private collector. We gave it a gentle cleaning, calibration and tuning, and we were off to the races. All original. Fully polyphonic... and patchable. Sounds... stunning."
