Korg PS-3100


Released: 1977

MSRP: Y490,000


Fully "Polyphonic Synthesizer", similar to the Moog Polymoog. Patch points and dual limiters give it capabilities similar to a modular. Architecture Class: Conventional (subtractive).

Ebay Description:

The Korg PS-3100 is a 48 key (fully polyphonic) synthesizer, featuring a single oscillator (triangle, saw, square, pulse waveforms), resonant low pass analog filter, dedicated ADR filter and amp envelopes (optionally externally triggered), LFO (routed to pitch and filter), ensemble effect, 3 resonators (with a dedicated LFO), S/H, voltage processor, and patch points.
