This video captures some early experiments, by Richard Devine, with Native Instruments' The Finger:
I was running some of my drums on a track in Logic's Flex mode, slightly drawing in graphic tempo changes, and automating all the parameter twist knobs drastically, while programming every MIDI parameter I could assign on the piano roll editor, Doing more then my two hands could do=) Just letting it all go crazy. Some strange interesting results indeed. =)
The Finger is designed to be a musical tool for live sound-mangling.
