Along with the D-5, D-10, and D-110, the D-20 is a second-generation Linear Arithmetic (LA) synthesizer that uses attack transients coupled with single-cycle waveform samples to generate sound. It is patch-compatible with the other second-generation D-series synths but not the first-generation D-50.
Although the sound engine is identical to the D-10, the D-20 has an onboard 8-track sequencer with rhythm track and a 3.5" floppy drive that can store 35,000 notes of song data per disk.
The Roland D-20 is compatible with the PN-D10 series of expansion cards.
