Visit http://georgewhiteside.net/projects/diskette-organ/ for more information! Test run of my (d)iskette (O)rgan doing Toccata & Fugue. People have made floppy drives sing before, but this is my personal take on it. Features two 3 1/2" drives and two 5 1/4" drives connected to a PIC18f14k50 microcontroller. It interfaces to any MIDI source via MIDI over USB.
