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.

The single VCO still sounds rich enough - they are divided down by top-octave divider ICs, now difficult to replace,to give the full range. They sound good due to the waveshaping carried out on the square wave source. There is enough patching capability, with voltage processors, to give a very good modular system in terms of flexibility. The built-in ensemble is a bit noisy, but that, along with the triple resonator, makes very effective sounds. Mine's a bit battered casewise but the front panel is substantial as is the internal construction.
