Responding to Bill Masterman's question on "A" roll tracker bar hole
assignments, the following appears in "Rebuilding the Player Piano" by
Larry Givens (book borrowed from Geo. McClellan):

  Hole 1...Soft pedal
  Hole 2...Sustaining pedal
  Hole 3...Rewind to play
  Hole 4...Lowest playing note
  Hole 61..Highest playing note
  Hole 62..Additional instrument on
  Hole 63..Rewind
  Hole 64..Mandolin on
  Hole 65..Shutoff

I am not sure if there is a standard for actual note assignments for
holes 4 through 61, but will check my instrument (Simplex Player) and
let you know, if this info is important for your application.  Maybe
Robbie knows ???
