I used this as my sound module for kick drum triggers. Comes with just the unit, other rack items/case in the pics are for sale separately. "The Procussion is a Proteus-era drum & percussion MIDI sound module released in 1991. It's a 32 voice multi-timbral sample based synthesizer with 4 MB of 16-bit percussion samples, selected from the Emulator III sound library and stored in ROM. There are hundreds of drums, percussion, mallets, vibes, etc. and they are all fully editable!" See my other ads for more music gear for sale. Cash only, no trades.
