Korg Poly-800 Analog Synthesizer

The Korg Poly-800 came out 1984 and is an interesting analog synthesizer with usable, interesting sounds. It has MIDI, runs even on batteries, and can be used as a remote keyboard. It was cheap, almost every musician could afford one - and can afford it even today. It has digital controlled oscillators (DCO’s). Not digital oscillators - they are just controlled digitally. Actually, it has just square waveforms. Combining different footages of squares you’ll obtain the usual saw, pulse and square wave
