Using an older DMC MIDI board to interface with organ pedals. The DMC is programmed with a very simple firmware the waches the pedal switches and sends MIDI note on messages from 12 to 24 (C1 to C2.) The pedals originally were "low note priority," and I had to do a little work on them to make the pedals polyphonic. With minimal effort, the firmware could be changed to alow for transposition or octave shifitng, sustain, etc.
