Korg Poly-61

The KORG Poly-61 (PS-61) is an analogue programmable polyphonic synthesizer released by Korg in 1982, as a successor to the Polysix. It was notable for being Korg's first largely "knobless" synthesizer - featuring a push-button interface for programming, dispensing with the Polysix's knobs and switches. The Poly-61 also uses digitally controlled analog oscillators or DCO's (Roland's Juno-6 had made the same leap the previous year), in place of the Polysix' VCOs. The Poly-61 also boasted double the amount of patch memory (64 memory positions versus the Polysix's 32), but did not feature its predecessor's on board effects.
