Korg PS-3100

Korg PS-3100 Image

The PS-3100 Analogue Synthesiser has monstrous polyphony - one built-in VCO, VCF, VCA, and EG for each of the keys on the keyboard for a total of 48 synthesizer circuits and polyphony! It's VCF has three resonant filters, plus there's a ring modulator, tremolo modulator, and LFO. However it lacks some rather basic features you would like such as patch memory.

Its successors, the PS-3200 and PS-3300 have far greater potential, but the PS-3100 is the only one which is built as a single compact personal synthesizer with its built-in keyboard. The modules are completely separate and inter-connected using Korg's standard patching system. You create sounds by patching and twisting knobs, very similar to Korg's MS-series.

How can you complain about a synth from 1977 not having patch memory? The MS-20 doesn't have patch memory either, nor has the Minimoog. The info still irritates me every time I read it.

I deeply regret selling mine. Tangerine dream used one back in the 80's as did Michael Garrison. The filters are pretty great. The "wood" on the front is cheap veneer and peels off easily and this machine is really heavy, nearly 70 pounds. Getting one maintained is a real trick as most repair places have never seen one. You can connect the patch bay to some modulars to breed new sounds. With a few patch cords you can make nice sonics. Using effects and an external sequencer is a good idea also. It uses octave dividers to achieve 48 note poly.

Wonderful...! I just got me one. Bought it *faulty* - and I had it fixed the next day. What a machine... underrated.

The first synth with n-key polyphony- even most of today's keyboards couldn't do that.

Found one of these in a skip, took it home and plugged it in.
Sadly the keyboard had failed, anyone know a fix?
