"The Pearl SC-20/40 are unique among electronic drum modules of the 80s, using what Pearl called "DWAP" (Digital Wave Analogue Processing) synthesis -- basically digital samples with digital and analogue processing available for pretty dramatic tweaking of the sounds. A truly unique tone generator for creating truly unique percussion textures. This version (the SC-40) has 4-voice polyphony for use with a full set of drum and cymbal pads (so you can play both arms and feet simultaneously). (The SC-20 was a two voice polyphony version meant for use with a few pads as add-on to an acoustic drum kit (where no more than two voices would be needed simultaneously))"
