I need a MIDI system for a Welte Theatre Concert Organ (electro-
pneumatic) in Rüdesheim, Germany.  The organ has two manuals, with 60
keys per manual, and a pedal with 30 keys.  It uses 71 registers, 21
effects, and 18 swellboards, and operates on 11-13 volts.

The MIDI System should be able to record and play at the same time.
