Jomox M.Brane 1_1

From the User Manual: 
The M.Brane 11 is a great sounding, dedicated percussion module with a real analog sound production. Actually it is a single voice analog synthesizer which is optimized for producing membrane-like snare/percussion drum sounds. The M.Brane 11 is fully controllable by Midi. Furthermore, there is an audio input provided to trigger the sound by a drum pad piezo pick up or an external audio signal. The usage of this unique drum module is simple and self-explaining at most points. We recommend though to read this manual carefully to let you quickly explore all the M.Brane 11's amazing musical possibilities.

From my use: 
I used this to build a library of odd sounds for interesting foley and soundscapes. Nice creation tool. I don't get enough use out of it. It's really nifty that you can connect it to a modular and trigger it externally.
