Absolutely perfect condition Creamware Pro-12 synth. Everything works as it should and it sounds fantastic. I've A/B this against my own Prophet-5 (rev 3.2) and it's so close you can hardly tell the difference in my opinion. Each knob sends a receives CC so you can also use this to program VSTi Prophet software instruments. Great effects built-in. 12-voice poly, or 6-voice unison with detune, or stack all 12 voices for monster unison. Velocity sensitive AND aftertouch destination - so think Prophet T-8! Latest OS installed. Comes with original editing & librarian software CD-ROM and power adapter. Software runs fine on my Win-10 64-bit machine (but I cannot guarantee this will the case on your computer).
