Play Guitar Hero Games using any MIDI Instrument

Play Rhythm Games using any MIDI Instrument: "Since I injured my middle left finger playing Guitar Hero 2 way too much when it came out, I've been dying to get back to playing it. But my finger hasn't healed. I was holding the neck too tightly on the X-plorer guitar controller and it hurts to bend it anymore. I've never had an injury playing the drums, so I thought 'wouldn't it be great to be able to play Guitar Hero on the drums?' So I thought about how that might be accomplished... researched, implemented, borrowed, and here I outline the finished product."
