Aeolian 116-note Player Pipe Organ Console Tabs
By Bob Taylor

I can offer some insight into the two questions posed by Howard
Towlson in MMD 071228.  The Tab or Stop pull marked "Pedal Augment"
should make the lowest 13 notes of the pedal play coupled up one
octave.  Thus each single note played in the lower 13 range results in
two notes (octaves) playing.  The result should occur both with manual
and roll playing.  This is the way my console is wired.

When 58-note rolls are played on the 116-note organ, the 58-note
selector switch connects the lower tracker holes to both manuals.  The
upper holes are not connected to anything.  The "Reverse-Normal-Unison"
coupler switch should be in the "Normal" position for the 58-note switch
to function properly.

If the 58-note switch is missing, a new switch should be easily installed
as the entire switching operation is carried out by the ladder switch
stack that is controlled by the "Reverse-Normal-Unison" coupler.  Since
the upper holes are not used, and since both manuals are played in
unison, the crescendo pedal will work just fine in this configuration.

It sounds to me that when Howard plays 58-note rolls, the top row of holes
are still active.  That can sound horrible if the stops are drawn for
the upper manual, as by the crescendo pedal or other means.

I hope this helps, if not, let me know.
