The 19" rack mount Roland U-220 RS-PCM Sound Module is derived from the Roland U-20 Keyboard , first released in 1989. The U-220 is also described by Roland as a "Multi-Timbral Synthesizer Module". The RS in the model name stands for Re-Synthesized, as the synthesizer engine can play back a modified version of stored PCM (Pulse Code Modulated) samples.

A dual oscillator, fully analogue, battery powered, ribbon synthesizer that fits in your pocket! With the edgy X-MOD from the Mono/Poly and the original MS-20 VCF filter, there's plenty of Korg heritage inside, as well as being able to apply that filter to any audio source via the Aux input jack - you really can go anywhere analogue!
