Korg Mono/Poly

The Korg Mono/Poly (MP-4) is a 44 key "mono-polyphonic" analog synthesizer manufactured by Korg from 1981 to 1984. This keyboard is the sister synthesizer to the Korg Polysix. It has four highly stable voltage-controlled oscillators (VCOs), a 4-pole, self-oscillating low pass filter (LPF), several modulation capabilities and pseudo-polyphony (paraphony).
Notable users are Johnny Jewel, MGMT and Erasure’s Vince Clarke. "It's like playing four cheap synthesizers at once” was Clarke’s observation of playing it.
