Expression Shoes and Controls
The Rodgers T797 has two expression shoes which are used to control the volume of the organ.
The left shoe normally controls the volume of the Great and Pedal divisions and the middle shoe
controls the volume of the Swell division.
See figure 3 below .
Figure 3. Expression and Crescendo Shoes
When an expression shoe is pressed forward, the volume of the division increases; when the shoe
is drawn back, the volume of the division decreases. The position of the two expression shoes are
displayed on two expression indicators, located on the right-hand side of the coupler rail.
There are also a number of very useful features which allow you to modify the way the organ is
expressed (i.e., how the volume is controlled). Each of these particular controls is activated by a
thumb piston which can be set in a general combination. If the thumb piston is lit, the control is
activated. These controls are each described next.
Crescendo Pedal and Controls
The slightly raised shoe on the right is the Crescendo shoe. This shoe gradually adds a
predetermined selection of stops as it is pressed forward. It does not affect the stops already in
use on the organ but merely adds to them as the Crescendo is activated. Closing the Crescendo
shoe subtracts the stops in reverse order.
Stops added by the Crescendo shoe do not light as they are activated. A Crescendo indicator
which shows the position of the Crescendo shoe is located on the right-hand side of the coupler
rail next to the two expression indicators.
Transposer
The Transposer allows you to change the key of music played. Commonly, this is used to
accommodate a soloist or instrumentalist who prefers accompaniment in a different key than
what is written or to easily raise or lower the pitch of a hymn. The Transposer position is
