Aeolian 116-note Player Pipe Organ Console Tabs
By Pete Knobloch

In MMD 07.12.28, Howard is asking about a control call "pedal augment"
on his 116-note player.  I should say that I don't have a console but
I do have a standalone player that someone built up from spare parts.

If you look at the switch stack of the player that connects to the
lower holes of the tracker bar, the lower 13 notes have 2 sets of
contacts per note.  One contact will go to the Normal/Reverse switch
contacts while the other will go to the 13 contact switch that you
talked about.  When the switch is turned on, it connects the lower 13
playing notes to the pedals.  To get these notes to play, you have to
turn on at least one pedal stop and have the pedal augment switch
turned on.  There are printed instructions on the roll that read "Pedal
OFF" and "Pedal ON" which determine if the augment switch should be
turned ON or OFF.

As far as adding a switch so that you can play the 58-note Grand rolls,
I added a DPST switch that effectively disabled the upper playing holes
on the tracker bar from playing.  I wired the switch in such a way that
the Reverse-Normal-Unison operation would still work when switching the
lower playing notes on the tracker bar to either the Great/Swell/Both
keyboards.  I can't give any details as how you could add this to your
console since I don't have one.  I would think that it could be added
into the switch logic that controls the 116-playing notes of the player
that goes to the 116 keyboard contacts.
