A determined fellow named Forrest set out on a three-day mission to build a foot pedal-based midi controller using an old keyboard PCB and fifteen sustain pedals he found on clearance at various Radio Shacks within a 60 mile radius. He wired the pedals to the PCB, which was connected to a laptop running a virtual keyboard program -- essentially turning the contraption into a QWERTY piano. The output then gets sent to his Roland guitar / synth via USB midi interface, allowing him to jam on his axe while also making sweet synth sounds with the pedal "keys."
