I too like 65-note piano rolls.  I often find that early arrangements
are in fact only 58-note, copied directly from 58-note masters.
I sell many 58-note organ rolls each year, so why the prejudice against
65-note rolls which have a larger scale?

I use 65-note rolls on an Aeolian Pianola Pushup which allows me to
play them on a piano, on a modern keyboard with 100 voices/sounds
(eventually to be linked into computer to record rolls), and also on
a pipe organ at a local church where I am able to use couplers to link
the Great and Swell manuals plus Pedals so they can all be played by
the pushup.

I can play the 65-note rolls on a Phoneon reed organ -- it has only 61
keys for hand-playing, but has 65 reeds for playing from the rolls,
including a 16-foot pitch reed rank at the treble end of the instrument
to bring down the pitch of the 1920's and 1930's dance rolls so they do
not sound squeaky.

I also play 65-note rolls on a player piano, so they are far more
versatile to play on different machines than 88-note rolls which are
only suitable to use on player pianos.

The titles are excellent: many early ragtime tunes by George M. Cohan
were not issued on 88-note; the early marches and two-steps are just
as lively as 58-note organ rolls.

I agree that they are not the best for serious classical tunes, but
for popular music of the day (1900-1908) 65-note rolls are just fine.
