Bass Coupler
The name of this feature is derived from the historical term Basso Continuo, meaning
thoroughbass. When the Bass Coupler is engaged, the piston lights. Any selected stops or
couplers in the Pedal division sounds from the lowest key being played on the Great manual.
This provides a pedal bass sound without actually playing the pedalboard.
In the default setting, the Bass Coupler affects keys 1 through 24 of the Great manual, but its
range is programmable up to key 32 (top of the pedalboard range).
Setting Bass Coupler Range
1.
Press and hold the SET piston, and press BASS, which begins flashing.
2.
Release both pistons.
3.
While BASS is flashing, press a key that corresponds to the highest note the range is to
extend. Any note from key 1 to key 32 may be selected. After the selected key has been
pressed, BASS turns off.
Note: When a key is pressed to set the range, no sound is heard even if stops are on, so no
disturbance is made if programming during a performance.
4.
To use the new range, press BASS. This range is saved when the organ is turned off.
Note: The Bass Coupler can only be set in General combination pistons.
Transposer
The Transposer is the default menu setting in the Console Display. Turning the Select Knob
while TRANSPOSER 0 is displayed lowers the pitch of the organ as much as four semitones
(half steps) and raises the pitch as much as four semitones.
Note: To select menu items other than the Transposer, it is necessary to first hold SET, and then
turn the Select Knob.
Master Tuning
The Rodgers T837 can easily and quickly be tuned to a piano or musical instrument not at
standard concert pitch (A=440.0). The Master Tuning adjusts one-half semitone sharp or flat.
If the instrument has been augmented with pipes, the Master Tuning feature is used to bring the
electronics in tune with the pipes. The pitch returns to A=440.0 when the organ is turned off.
Adjustments to the tuning cannot be made unless the Master Tuning is unlocked.
Locking and Unlocking Master Tuning
1.
Press and hold the SET piston.
2.
Turn the Select knob clockwise (right) until the Console category shows on the display.
3.
Release the SET piston and turn the Select knob until the Master Tuning menu is visible.
