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 helpful 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.
Selecting Fixed Velocity
To set a Fixed Velocity value for a MIDI coupler:
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 VELOCITY appears in the display.
4. Rotate the Alpha dial to select the desired velocity value (2-127).
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 velocity selection procedure is complete. Combination pistons that are set while the
MIDI coupler is activated will also store the velocity setting. A MIDI Save may be
performed to save this setting as the default. See “MIDI Save” on page 51.
Expression Velocity (EXP)
With Expression Velocity, the velocity value is determined by the position of the related
expression shoe when the note is played. As the expression shoe is pushed further open,
for example, the velocity value of notes played increases; as the expression shoe is
closed, the velocity value decreases. This mode allows you to control both overall level
and the attack characteristic of instruments by moving the expression shoe.
When in Expression Velocity mode, the volume value for the coupler is set to 127
(“full”), and movements of the expression shoe will not change the MIDI volume
message; only the expression value of notes played will change. This means that notes
which are held down will be unaffected by movement of the expression shoe—only new
notes played will respond to changes in the shoe position.
Also, instruments controlled by couplers set in Expression Velocity mode will typically
be much louder when the expression shoe is pushed open—because both the volume and
