The Octave Shift selection procedure is complete. Combination pistons which are set
while the MIDI coupler is activated will also store the this setting. A MIDI Save may
be performed to save this setting as the default. See “MIDI Save” on page 75.
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 MIDI coupler piston, and these settings can then
be saved on combination pistons.
To summarize:
•
Fixed Velocity (keyboard sends a fixed value between 2-127)
•
Expression Velocity (velocity value is controlled by the position of the
expression shoe)
•
Keyboard Velocity (keyboard responds to velocity from player’s fingers)
Fixed Velocity
With Fixed Velocity, the same velocity value is used for all notes played by a MIDI
coupler. The velocity can be set to any value from 2 to 127.
It is often useful to use this parameter to adjust the overall volume and attack
characteristic of sounds controlled via MIDI. Reducing the velocity value would make
an instrument softer; increasing the value would make it louder.
This allows you to adjust the level of a sound in relation to organ stops or other MIDI
sounds. For example, if you were controlling two sounds, one from
MIDI GT A and one
from MIDI GT B , the Fixed Velocity value could be used to adjust the level of the
sounds in relation to each other. If the sound controlled by MIDI GT B were too loud,
Instead of saving, you may press and hold General Cancel (‘ 0 ’) and momentarily press
SET to return MIDI couplers to their defaults. This Reset procedure also returns
Voice Palette selections to their defaults.

On instruments with wooden keyboards, keyboard velocity control is not available.
