Press the thumb or toe piston to turn on, and press again to turn off. All reversible thumb pistons
light when engaged. Each specific function controlled by a reversible is also discussed
elsewhere in the manual.
Expression Shoes and Controls
The Rodgers 657/677 has two expression shoes that are used to control the volume of the organ.
The left shoe normally controls the volume of the Great and Pedal divisions and the right shoe
controls the volume of the Swell division. 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.
Crescendo Pedal
The CRESC tab must be engaged for the right shoe to act as a Crescendo pedal. When
activated, 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
that shows the position of the Crescendo shoe is located on the right side of the coupler rail.
When the
CRESC tab is lit, the expression for Great, Pedal and Swell divisions are all
assigned to the left expression shoe, allowing you to easily control the volume of the entire
organ. The other shoe then automatically acts as a Crescendo pedal.
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. When activated, the Transposer
will also transpose incoming MIDI channel note events. The Transposer position is normally
shown in the Console Display. If another screen appears in the display (i.e., while programming
a specific parameter), you can easily return to the Transposer by pressing the General Cancel (
0 )
thumb piston.
Turning the Select knob while TRANSPOSER 0 is displayed lowers or raises the pitch of the
organ as much as four semitones (half-steps). Rotating the Select knob clockwise raises the pitch
of the organ by semitones; rotating counter-clockwise lowers the pitch by semitones.
Pressing General Cancel returns the Transposer to ‘ 0 ’, (no transposition).
Tremulants
Tremulants create a change in pitch (sharp and flat), amplitude (volume) and timbre (tone
quality). The use of the tremulant adds warmth and expressiveness to solo or small ensemble
combinations. It is not common to use tremulants in larger classical ensembles. In some
romantic ensembles, tremulants are used judiciously. In some gospel and evangelical musical
traditions, tremulants with a wider and deeper excursion are frequently used.
There are two types of tremulant controls on the Rodgers 657/577; divisional tremulants that
affect only the stops in their respective division and general tremulants that affect all divisions.
