The Korg MS-20 is a patchable semi-modular monophonic analog synthesizer which Korg released in 1978 and which was in production until 1983.[1] It was part of Korg's MS series of instruments, which also included the single oscillator MS-10, the keyboardless MS-50 module, the SQ-10 sequencer, and the VC-10 Vocoder. Additional devices included the MS-01 Foot Controller, MS-02 Interface, MS-03 Signal Processor, and MS-04 Modulation Pedal.

It goes together with s very good old-school sequencer from Korg. Designed for the MS series synthesizers and using Korg's CV / Gate control the SQ-10 sequencer can really surprise you with some groovy basslines. Three channel output allows pitch, tone color and timing variation. Use the knobs to adjust and build up a sequence. Sure it's limited to 12 steps (with a max of 24) but when you hook that up to your MS-10, MS-20 or MS-50 you can get some pretty cool TB-303 like stuff happening. Because the SQ-10 outputs CV (Control Voltage) it can also be connected to the Oscillators, VCF (filter) or LFO's of your MS synths for even cooler tricks. Using a CV / Gate converter allows you to use the SQ-10 with other Roland, Moog, Sequential and even MIDI synthesizers. It's definitely a fun instrument which allows you to program basslines just like they did back in the early days!
