"The
Alien-Devices modified Roland TR-505 is a MIDI drum synthesizer that is capable of producing thousands of new and unique synth drum sounds and percussion patterns. The mods can effect the drum sounds in subtle or drastic ways creating synth tones, digital filtering, distortion, bizarre beat warping, and strange electronic textures. These units are great sample sources as well as stable live instruments and are fully MIDI capable."

Update: Looks like they have a Bent Alesis HR-16 up as well:
