Korg MS-20

Raw, wild, and wonderfully unpredictable.
The Korg MS-20 is a semi-modular analog synth known for its aggressive filters, punchy oscillators, and patchable flexibility. At Rupert Street Recording, it’s our go-to for gritty basses, piercing leads, and experimental sound design that pushes boundaries. Its hands-on interface invites creative exploration, making it a favorite for producers who love to get their hands dirty with sound.

The MS-20’s powerful self-oscillating filter and external signal processor made it a favorite among early electronic and industrial artists—and it can even process guitars and vocals in wild, unconventional ways.
