The Procussion is a 32 voice multi-timbral sample based synthesizer module that plays percussion instruments. It contains hundreds of different drum and percussion samples, which can be played from a keyboard or MIDI drum pad. The Procussion has 4 MB of 16-bit percussion samples, selected from the Emulator III sound library and stored in ROM.

The Procussion can manipulate these basic samples into an almost limitless number of entirely new percussion sounds, combining parts of one instrument with another or with any of a selection of digital waveforms stored in ROM. The 16 bit samples are arranged into 128 kit locations, 64 of which are user-programmable.
