I am seeking information on the "58-note standard organ" roll,
10.125 inches wide, 58 holes, 6 holes per inch, on spool with
pinned ends.  Could anyone provide or suggest where I might
find the description of notes and controls allocated to each
longitudinal channel?

I have constructed an electronic pianola (no vacuum) that plays
88-note rolls and I wish to extend the principle to other roll
types; see  https://optop.cartography.id.au/
