Many manufacturers of MIDI sound modules have added—or will soon add—support for
GS Format.
Octave Shift
Normally, sounds controlled by MIDI couplers play at concert pitch; playing middle C on an
organ keyboard with a corresponding MIDI coupler active will cause middle C to be heard.
The Octave Shift control allows you to shift sounds controlled by MIDI couplers up or down
by one or two octaves. Each MIDI coupler can be shifted independently.
This is tremendously useful. When controlling a single sound from a keyboard or pedal,
Octave Shift allows the instrument to play in a range that may be more appropriate; for
example, you can shift a Tuba down one octave so that it plays at a more normal pitch.
Shifting the Octave of a MIDI Coupler
To shift a MIDI coupler up or down by octaves:
1. Press and hold the SET piston.
2. Press the desired ORCH/MIDI tab ( SWELL , GREAT , or PEDAL ). The tab
flashes, indicating a MIDI setting can be made. This is called the MIDI Set
Mode.
3. Turn the Select knob until OCT appears in the display.
4. Rotate the Alpha dial to select the desired setting ( UP 2 , UP 1 , NORM , DN 1
or DN 2 ).
5. Press either the flashing ORCH/MIDI tab or General Cancel (‘ 0 ’) to exit, or
rotate the Select knob to adjust another MIDI parameter.
The Octave Shift selection procedure is complete. Combination pistons that are set while
the MIDI coupler is activated, will also store the setting. A MIDI Save may be
performed to save this setting as the default. See “MIDI Save” on page 51.
Velocity
MIDI note velocity controls the attack quality and loudness of MIDI sounds. It relates to the
amount of force used by the organist when striking a key and ranges from a value of 2
(extremely light) to a value of 127 (extremely hard). In addition to obvious changes in
volume at higher velocities, the timbral nature of sounds can also change, usually
characterized by an increase in high frequency content.
Rodgers organs can send out a constant (fixed) velocity value from the keyboard, a
changeable velocity value sent relative to the position of the expression shoe, or a keyboard-
responsive velocity controlled by the actual force of the fingers. Your choice of velocity
control can be individually selected on each ORCH/MIDI tab, and these settings can then be
saved on combination pistons.
