MIDI Pedalboard Page
A MIDI Pedal Board Project
This page describes modification of an old organ pedal board to output MIDI signals. The purpose is to use it with a MIDI keyboard(s) and the Hauptwerk organ simulator program.
The pedal board came from an old analog electronic organ (Schober Recital Organ), but pipe organs use similar units and are sometimes available surplus.
The switches are mounted on copper "nails" which are tapped into predrilled holes in the wood frame. The "nails" are actually just short pieces of #14 bus wire as used in electrical house wiring. Magnets are mounted on steel hex-head screws which are partially screwed into the wooden pedal boards. No glue is used, the magnets just stick by themselves.
The advantages of this arrangement are that the switches are soldered to the copper "nails", and adjustment is made by simply bending the nails back and forth, and/or turning the magnet screws in and out.
The keyboard encoder was purchased from Classic Organ Works in Canada www.organworks.com. This a 61-key unit, and the excess above the 32 pedal notes was eventually used to sense other organ control positions. This encoder seemed to be the best buy because it includes a built-in MIDI-merge function. The encoder works perfectly.
