Like new Evolver by Dave Smith (Sequential Circuits). This is the desktop version so no keyboard. You can use it as a stand alone sequencer, hook up a midi keyboard, or use as an effects processor for whatever you want. This thing is stacked like no other sequencer on the market- 2 analog and 2 digital oscillators, 4 LFO's, and 4 separate fully programable sequences, 5 delays, distortion etc... Perfect condition cosmetically and functionally. Comes with original power supply and manual. Might consider a trade for an analog synthesizer or tube amp. Thanks for looking.
