Tremulants; Adjusting The Tremulant Settings; Tutti - Rodgers 835 Manual

Tremulants create a change in pitch (sharp and flat), amplitude (volume) and timbre (tone
quality). The use of the tremulant adds warmth 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 835. The Divisional tremulants
(Great, and Swell) affect only the stops in the respective division. The Swell trem also
controls a separate trem for the Voix Humaine. There are two General tremulants: the Flute II
tremulant affects all manual flute stops simultaneously, and the Main II tremulant affects all
remaining manual stops simultaneously.
All tremulants may be individually adjusted for rate and depth by performing the
following procedure:
 ADJUSTING THE TREMULANT SETTINGS:
1. Press and hold the SET piston.
2. Turn the Select Knob counter clockwise (left) until the Console Display reads:
3. Turn the Select Knob until the cursor is on the tremulant name. Note: Please refer
to the "835 User Menu Items" section.
4. Rotate the Alpha Dial until the Console Display reads the tremulant to be adjusted.
5. Turn the Select Knob until the cursor is on the rate.
6. Rotate the Alpha Dial until the Console Display reads the desired tremulant rate.
Note: The range is from -9 to +9. The rate setting may be previewed by selecting
a corresponding stop and playing a note while the adjustment is made.
Note: These settings are retained when the organ is turned off.
There are times when a full organ registration is needed immediately. The Tutti on the
Rodgers 835 can be set with any combination of stops. Press either the TUTTI piston or the
TUTTI toe piston to access the Tutti combination. These pistons are reversible, so simply
press again to cancel. When Tutti is in use, the top four segments of the Crescendo/Tutti
indicator light red. The Crescendo/Tutti indicator is located on the coupler rail to the far right
of the tilt tabs above the Swell manual.
