On to my second project (the first was a pedalboard midi conversion with a Brain Jr.).
Have a Wurlizter Omni 3500 dual keyboard that I would like to convert to MIDI. however, the schematics indicate a 12 x 4 diode matrix for upper and lower manual. The pedalboard is a 4 x 4 matrix.
Can this configuration be accomplished with the Brain without re-wire?
