The programmable 6-voice polyphonic analog synthesizer released in 1981: Polysix.
Everything from Polysix has been completely reproduced: the 1VCO (with sub-oscillator) /1VCF/1VCA/1EG configuration which enables a choice of SAW/PW/PWM waveforms, the chorus/phase/ensemble effects, and performance functions such as chord memory, arpeggiator, and unison.
