Normally, the Solo division expresses with the Swell; when the Swell expression shoe is moved,
both the Swell and Solo divisions change in volume. By activating the SOLO EXPR CH
piston, the Solo division will express from the Choir expression shoe, rather than the Swell
expression shoe. This feature gives you the ability to control the volume of the Swell and Solo
divisions independently.
All Swells
There are times when it is desirable to use a single expression shoe to control all divisions under
expression. When the ALL SWELLS piston is lit, the Choir, Swell and Solo divisions are all
assigned to the Swell expression shoe, allowing you to easily control the volume of every
enclosed division.
! If ALL SWELLS, GT-PD ENCL and FEST TR ENCL (FFF REEDS ENCL) are all
activated, the entire organ is enclosed and can be expressed by the Swell expression
shoe.
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
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 (O) or STOP thumb piston until TRANSPOSER appears in the display.
Turning the Select knob while TRANSPOSER 0 is displayed lowers or raises the pitch of the
organ. 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 O, (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 available on Rodgers organs, divisional tremulants that
affect only the stops in their respective division and general tremulants that affect all divisions.
If there is a Solo division on the organ, up to four divisional tremulants may used. One each for
the Great, Swell, Choir and Solo; the first three are controlled by a tab or drawknob within each
division, while the Solo tremulant, if applicable, is located on a thumb piston.
