A true classic of the late pre-MIDI era, the Korg Mono/Poly is a four oscillator monster, which can be used in a variety of voice modes. The spec on paper for the Mono/Poly is pretty amazing: four oscillators, two LFOs, two ADSRs, poly, unison, and chord memory modes, arpeggiator, and the tremendous cross modulation and frequency modulation section. The sound is rich, detailed, and expressive. This synth was just serviced and is in perfect working order!
Cosmetically the graphics and paint are sharp and clean with nothing out of the ordinary, wood sides show average wear and tear.
