The Korg Polysix is a six-voice programmable polyphonic analog synthesizer released by Korg in 1981.
The synthesizer's main features are six-voice polyphony (with unison and chord memory voice assignment modes), 32 memory slots for patches and cassette port for backing up patches, and an arpeggiator.
At the time of its release, the Polysix, along with the contemporary Roland Juno-6, was one of the first affordably priced polyphonic analog synthesizers. It cost about twice as much as the competing Juno-6 but had more features and 'real' VCOs in place of the Juno's DCOs. It also had on-board patch storage and backup which the cheaper Juno lacked until the upgraded Juno-60 model.
Korg developed the Polysix with an eye on the Sequential Circuits Prophet 5, trying to provide some of the features found on the more expensive synth in a compact, reliable and much cheaper design. While not as powerful, it used SSM2044 4-pole voltage-controlled filters, giving the Polysix a warm, rounded, and organic sound.
Although the Polysix only had one oscillator per voice, it also featured built in chorus, phaser, and 'ensemble' effects (using a 'bucket brigade' analog delay line design), to provide a fuller sound.
The Polysix had a straightforward synthesis architecture. Each voice had one oscillator with sawtooth wave, variable pulse wave, or PWM outputs. The PWM section had its own LFO. In addition, there is a sub-oscillator that allows the addition of a square wave either one or two octaves below the main VCO pitch.
