Ebay Description:

The Roland CM-64 is a desktop digital synthesizer, combining the CM-32L and CM-32P engines (editing via MIDI only). The CM-32P engine is a (aftertouch and velocity sensitive) 31 voice (6 part multimbral), featuring 1-6 oscillators (99 samples) per patch (64 patches), AR envelope, LFO (with attack), reverb/chorus, and PCM card slot. The CM-32L engine is a (velocity sensitive), 8-32 voice (9 part multimbral), digital synthesizer (editing via MIDI only), featuring 1-4 oscillators (sample or resonant low pass filtered saw/square), dedicated pitch/filter/amp 5 stage envelopes, LFO, reverb, 128 presets.
