I wish to express my gratitude to all those who have sent comments,
suggestions, etc., regarding my query on the suitability of using a
player piano roll mechanism to operate a pipe organ.  The discussion
has given me much food for thought; I'll communicate with the list as
to the path I decide to follow and let you know of the result.  I'm
sure some player piano music is suitable for pipe organ; after all,
what was the FotoPlayer (sic?) about (although probably not 'classical'
selection)?

Thanks to all,
Robert Pelletier
