This was the most modular, most complex, and therefore most expensive of Korg's MS line. It was designed to be an expander and, therefore, had either Hz/volt or volt/octave interfaces. The MS-50 was totally modular, in that there was no hard-wire patching at all. A monophonic synth, the MS-10 had one VCO, two VCFs, two VCAs, a voltage controlled LFO, two ADSRs (with normal and inverted outputs), pink and white noise, a signal inverter, multiples, a ring modulator, a voltmeter, sample and hold, and a headphone socket. It is designed to match the SQ10 analog sequencer.
