E-mu Procussion

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!

The sounds vary from acoustic to electronic and many sounds have stereo effects. Sounds can be combined/layered with up to four samples mixed into one drum sound or with any of a selection of digital waveforms stored in ROM. Each instrument also has many individual attributes such as tuning, volume, pan, etc. The sounds are arranged into 128 drum-kits, 64 of which are user-programmable. Each kit can have up to 24 drum samples assigned to it. In each kit, individual sounds can be mapped across the keyboard or set of drum pads. Up to 24 Zones may be assigned per kit.

Another feature is Stacks which can be made of up to 4 percussion Instruments. The instruments in a stack can be modulated in many ways or switched on and off depending on various parameters such as velocity or high hat pedal position, etc. A very complete and capable Drum & Percussion kit sound module of the same ilk as Alesis's D4 and DM5. It has been used by Front 242 and KMFDM.

It has good cymbals -- some of the best sampled drum machine cymbals I've heard.

I just scored one of these racks, the sounds in there are 16 bit classic 90's and sound real good, I think this unit is kind of rare I don't see to many of them around.

I have a feeling that this box has a lot of potential. That said, I'm not sure too many people have actually seen that potential in action. The PRO/CUSSION has excellent programmability but there is a sizable learning curve and no SYSEX files seem to be available for download. The preset kits are not very good so buyers should be prepared to construct their own. A lot can be done with this unit, albeit underneath a 16-bit ceiling. Still, I have to think there are more capable instruments out there.

i have this drum module. Sounds at first little bit cheesy, and outdated, but its a SYNTH and you have to program it. It has basic waveforms (sine, tri, saw, etc) and envelopes, and you can get some nice sounding kicks. You can switch drum kit with the main knob and sometimes the result is wonderful. Its very dry and need to process sounds with eq, fx. If you are a poor guy and do electronic/minimal/experimental music its a good choice. Very cheap and very creative module.
