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.
