Seek Music Rolls for 43-note Tangley Calliope
By Craig Williams
The larger crank organ scales (e.g., Raffin 31 and deVries 38)
fit within the 43-note calliope range. About 150 MIDI files of
these exist. They could be perforated as calliope program rolls
if someone has a MIDI-controlled punch for 6/inch.
