The Roland U-20 is a PCM-sample synthesizer, released by Roland in 1989. It was the keyboard version of the U-220 rack module, which was in turn a similar follow-up product to Roland's U-110 rack module of 1988.
The U-20 is described by Roland as a 'RS-PCM keyboard', where RS stands for ReSynthesized because the sound-engine can play back a modified version of stored PCM samples.
