Recently, I have been working on an Estey residence organ that has been
in the same family since 1912!  The 10-rank tubular pneumatic organ was
moved to the present residence in 1927.  By reversing the tracker bar,
the player will play 58- or 65-note rolls.

A "Y" is inserted in the top and bottom octave tubing to couple tracker
bar notes beyond the 61-note compass of the pneumatic relay.  This is
fine until the lowest notes of the 16 Bourdon are drawn in: tonal mud
can result.

There are many Estey player rolls.  None of them are "automatic" -- the
rolls must be hand-registered and expressed.  Many of the older 65-note
rolls are in poor condition with torn or missing leaders.  Most of the
selections are of a religious or classical nature.  There is one 65-note
roll that plays fairly well: "Burning of Rome" by E. T. Paull.  There
is no indication as to whether it was hand played.

The roll player itself is very simple and works on a pressure system
not unlike Aeolian.  Given its age, and generally unrestored condition,
I can only say the Estey product is amazing to still be operating
fairly well after 96 years!
