Released in 1981, the Korg Polysix was one of the first reasonably-priced instrument (alongside Roland’s Juno 6) retailing at around $1000. The Polysix sounds classy, big and fat and was also one of the first poly synths to feature built-in effects – chorus, phaser and ensemble.
The warm-sounding pure analog sound is powered by a 6-voice engine with one VCO per voice, a sub-oscillator, a filter section with control over the envelope amount and keyboard tracking, a flexible ADSR envelope, an LFO which could be routed to the oscillator, filter or the amplifier, a clever arpeggiator for its time, capable of memorizing and sequencing chords across the keyboard and the classic chorus, phaser or ensemble effects unit. The effect section was a key feature which made the unit popular as it became a tool to fatten up the sound even more.
The Polysix has been used by the likes of Jean Michel Jarre, Keith Emerson, Damon Albarn (Blur / Gorillaz), Tears for Fears and Eric Prydz.
