I have a homebuilt fairground organ having 320 pipes and playing
from the Carl Frei 72-key scale. I am seeking information on the
availability of a MIDI synthesizer that I can program to replicate
the sound of my organ to enable me to test run MIDI files in my
studio before playing them on the organ.

 [ Rich Olson built a dedicated computer to do the job. The output
 [ audio signal to the loudspeakers was synthesized using a "sound
 [ font" of live recordings of band organ pipes. The input data
 [ was from a "tracker bar image" MIDI signal that ultimately would
 [ control a perforator or a MIDI-controlled organ. The MIDI data
 [ was not compatible with the chromatic synth that is built into
 [ modern computers. -- Robbie
