Overview
The Korg Poly-61 is a six-voice analogue polyphonic synthesizer introduced by Korg in 1982. It was Korg’s first synthesizer to use a microprocessor for parameter control and patch storage, replacing the conventional knob-per-function panel of its predecessor, the Polysix, with a small button matrix and a single value slider. Each voice provides two oscillators, a filter, and dual envelopes, with 64 patch memories on board.
Origin & History
Korg released the Poly-61 to compete with other early-1980s polyphonic synthesizers that combined analogue voices with digital control. The microprocessor-driven interface reduced the front-panel real estate and lowered manufacturing cost, but it also made live editing slower than on knob-based instruments. A revised Poly-61M added MIDI shortly afterward. The line was a strong commercial success despite the interface compromise, and it has since become a sought-after instrument for its full analogue voice path and its early microprocessor-era character.
How It’s Played
The Poly-61 is played from a 61-key keyboard with patch numbers selected via the front-panel buttons. Editing requires choosing a parameter on the matrix and adjusting it with the data slider — fast for setting up a patch on a workbench, slow for live tweaking. The two-oscillator voice gives the instrument a thicker sound than single-oscillator analogue polys; the resonant low-pass filter shapes pads, leads, and basses cleanly. Without an arpeggiator or built-in effects, the Poly-61 relies on its raw analogue voicing for its appeal.
Cultural Significance
The Poly-61 sat at a transition point in synthesizer design — analogue voices controlled by digital interfaces — and is often cited in histories of how the workflow of programming a synthesizer changed in the early 1980s. The instrument appeared on a wide range of pop and electronic recordings of the period and has since gained a second life in retro production, where its full analogue voice path is appreciated despite the interface.
