I would like to know how rolls are arranged -- 88-note or other types,
with or without the music score -- for perforating by a perforator
mechanically driven by "electronics".  What is the degree of accuracy
in this process?

 [ Steve, it sounds like you're speaking of the process at Play-Rite,
 [ which is able to produce new music rolls for Wurlitzer band organs
 [ from MIDI files supplied by arrangers.  Perhaps Mikey Mills or
 [ Andy Park can explain the process.  The accuracy is scary -- all
 [ your errors are faithfully reproduced!  ;-)  -- Robbie
