“The Korg MS-50 Expander Module is fully-patchable, keyboard-less, single VCO monophonic analog synthesizer. It uses Korg’s Hz/V type of CV & Gate for control with other synths like the MS-20. It has lots of knobs and offers more patchability & power than any other MS synth. Other features include a ring modulator, voltmeter and Sample & Hold. It was also designed to complement the SQ-10 sequencer. It has been used by The Chemical Brothers, among others. The MS-50 is a rare model within the MS series. It has internal circuits such as a divider and integrator not found on the MS-10/20, which supported even more complex ways of creating sound. The voltmeter on the upper right-hand side of the panel captured the hearts of many synth players. Of course, it could also be played on its own by using CV/Gate signals.
Worked fine the last time it was used, but hasn’t been turned on in a while or fully tested (has been kept in a climate-controlled environment), so selling “as is.” Includes manual and schematics.” Click here to visit listing on eBay
