Duo-Art Organ Test Roll
By Bruce Clark

Although the years have rolled by ...  I once borrowed a Duo-Art Test
roll from someone to use in testing out a Duo-Art player organ.  As I
recall the roll was not in the best condition, but I do remember the
leader had a listing of the entire tracker layout at the beginning of
the roll.  This was far more important than seeing a few holes pass by
and hear a few notes play here and there, but no notation on the roll
as to what was happening or for what purpose.

Once you know what command each hole does, all you need is a piece of
masking tape, and a large pin.  The stop action is a general cancel of
everything at the beginning of the roll.  As I recall there was a per-
foration for on, and the same perforation a second time was off, for
different stops.

A few years ago, I made a photocopy of the tracker layout, and sent it
to the George Eastman House in Rochester as a gift when I heard they
were about to restore the Aeolian Duo-Art organ and player.  So far
they have not done this.  Hopefully they have preserved the photo copy
in their archives, and might send you a copy of it if you write to
them.
