MIDI Automated Pipe Organ Pedals

Bob Harris of Charlottesville, Virginia used two MD24 MIDI decoders and an array of 24-volt solenoids to automate the operation of the pedals on his Flentrop tracker pipe organ.  Cakewalk Music Creator sequences the pedals while the human operator concentrates on the manuals, aided by an MD24-controlled LED metronome.

Bob’s excellent video details the mechanical & electronic operation of the system.  Bob introduced the project at the HL forums in this thread.
