Michigan Synth Works Teases MSW-830 Desktop Synth

In our previous article we looked at Michigan Synth Works' MSW-810, a modern clone of the quirky Roland Compu Synth CMU 810. This early 80's beige-box was essentially an MC202 with special interfacing for an Apple II computer (plus CV/Gate for people who aren't vintage computer fetishists).

The instrument adds optional MIDI, but retains pretty much all of the quirkiness of the original device. Well, Michigan Synth Works have since been hard at work, mutating and redesigning this sweet little monosynth into an absolute beast. Just look at these specs!
