Tuning

The Rodgers 657/677 is set to standard concert pitch (A=440.0Hz). However, it can easily and
quickly be tuned flat or sharp to match the pitch of another musical instrument, such as a piano
or harp.
In instruments augmented with pipes, the Tuning feature can be used to bring the electronics in
tune with the pipes. The pitch retains this setting when the organ is turned off.
Normally, the Tuning control is locked and the Transposer is the only parameter in the default
display. However, when the Tuning control is unlocked, both the Transposer and Tuning
settings appear in the display; each can be easily changed.

Unlocking and Adjusting Tuning

To unlock Tuning and change the setting:
1. Press and hold SET.
2. Rotate the Select knob counter-clockwise until TUNING LOCK appears in the
display.
3. Rotate the alpha dial until ADJUSTABLE, or MANUAL ONLY appears in the
display.
4. Turn the Select knob until TUNING appears.
5. Rotate the alpha dial to adjust the tuning.
6. Press General Cancel ('0') to save your changes and exit.
The instrument will remember this selection when it is powered off.
In the Adjustable setting, pitch can be adjusted at the console or via an externally
!
connected MIDI device. In the Manual Only setting, pitch can be adjusted only from
the console.

Tremulant Controls

The first section of this manual described how tremulants are activated, what stops they control
and how they are often used. Another impressive feature of the 657/677 is the User-Adjustable
Tremulants. Although the tremulants are carefully set at the factory and adjusted when the
organ is voiced, the rate and depth may be modified for each to meet a particular musical need or
suit an individual taste.

Adjusting Tremulant Settings

To change the rate and depth for a tremulant:
1. Press and hold SET.
