The Blue Korg MS-20 FS is a faithful reissue of the original full-sized analog synthesizer featuring the circuitry of the iconic, late 1970s MS-20. Its versatile patching options, two versions of analog filters, and the ability to process external signals makes this diminutive powerhouse very attractive to the analog synthesizer aficionado.

A development team led by the original engineers strove to painstakingly replicate the MS-20, both in sound and form. The sound comes from an architecture featuring two oscillators (one with ring modulation) and envelope generators with hold and delay. The VCA (voltage-controlled amplifier) maintains the basic design of the original, but has been modified to produce less noise.

The high- and low-pass filters have a switch for early and late models, and feature resonance and distinctive distortion, which can deliver radical sounds when they are pushed into self-oscillation. Additionally, external sources such as an electric guitar or vocals can be used to control the synthesizer or have the source manipulated by the filters. A flexible hardwired patching system provides nearly endless possibilities.

The synthesizer features a MIDI In jack for receiving note messages, and a USB-MIDI connector that can transmit and receive note messages (there is no velocity information over MIDI, but you can modulate signal amplitude via VCA patch points). Connecting the unit to a computer allows it to be triggered from a sequencer. The Korg MS20 FS ships with a power adapter and ten patch cords.
