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.

Some models also feature up to two additional general tremulants, Main Tremulant II and Flute

Tremulant II. They will be located on thumb pistons labeled MAIN TREM II and FLUTE TREM II.

Both of these tremulants find their best use in gospel, theatre and evangelical music; the Main

tremulant affects Principal, String and Reed voices whereas the Flute tremulant affects Flute

voices. Divisional tremulants can be stored with registrations in both general and

corresponding divisional pistons; general tremulants can only be stored on general pistons.

Each tremulant can be modified easily to suit your tastes and needs. See the AG
