MIDI-file Standards for Controlling Orchestrions
By George Bogatko

Here's the MIDI layout I use for the Coinola and Cremona emulations.
Lay it out like this and it could be cut by Custom Music Rolls.  Tube
it like this and it could play an O-roll transcription.

The MIDI numbers are those used by CAKEWALK.

 [ MIDI note 60 is Middle C, as defined in the MIDI Specification,
 [ thus it will be the same number in every MIDI file.  Not so for
 [ the note names! -- Robbie

 19. Forward to play
 20. Unused on 90-hole tracker bar.

 24. Wood Block

The Coinola chromatic sections (accomp. and solo) play at pitch, with
no transposition.  Cremona (below) involves a transposition.

Here's Cremona:

 34. Violin on
 35. Violin off

 37. Flute Off
 38. Off Hi Piano*
 39. On Hi Piano*
 40. Mandolin on
 41. Mandolin off
 42. Sustain pedal

 44. Castanets
 45-108. Chromatic A to A (transposed one octave lower)**
 109. Fast Forward
 110. rewind
 111. (blank)
 112. shutoff

* The solo instruments double the piano from the high A down 32 notes.
The same range of the piano can be shut off to allow the solo
instruments to really play "solo".

** In other words, you'd tube the trackerbar ("midibar") to sound
an octave lower.
