The KORG Poly-61 is a programmable polyphonic synthesizer released by Korg in 1982, a digitally controlled successor to the Polysix. It was notable as it was the first Korg synthesizer to feature a pushbutton user interface, dispensing from the Polysix\'s knobs and switches. In 1984 a MIDI version, the Poly-61M was released featuring basic MIDI implementation.
