External Control Assignment - Yamaha SPX900 Operation Manual

EXTERNAL CONTROL ASSIGNMENT

The SPX900 allows two different parameters of a selected
effect to be controlled by optional foot controllers (Yamaha
FC7) connected to the front-panel EXT CTRL/FOOT VOL1
and 2 jacks. The EXT CTRL ASSIGN key is used to assign
the desired effect parameters to the foot controllers used, and
to set the required control range. External control assignments
made for an effect program can be stored in the user memory
area (51 – 99) along with the effect (using the STORE
function described above). so that the assignments made are
recalled whenever that memory location is selected.
1. Select the desired effect program.
2. Select the parameter to be assigned to an external foot
controller (PARAM, LEVEL, EQ or INT PARAM
parameters can be assigned).
3. Press the EXT CTRL ASSIGN key. The name of the
selected effect program will remain on the upper line of the
LCD. and one of the following parameters will appear on
the lower line:
In the actual display, "XXXXXXXX" will be the name of
the default parameter for the selected effect program. The
EXT CTRL ASSIGN key can be used to scroll forward
through the above parameters. and the SCROLL BACK
key can be used to scroll backwards.
4. To assign the selected parameter to the EXT CTRL/FOOT
VOL1 or EXT CTRL/FOOT VOL2 controller. use the EXT
CTRL ASSIGN or SCROLL BACK key to call the
"FVOL1 XXXXXXXX" or "FVOL2 XXXXXXXX"
parameter.

5. Press either the parameter
you called within the selected effect program will be
assigned to the foot controller indicated on the display
(FVOL1 or FVOL2).
6. Use the "MIN" and "MAX" parameters for the appropriate
controller to set the control range. If the parameter to be
controlled has a range of 0 to 100%, for example, setting
the MIN parameter to 20 and the MAX parameter to 80
will allow the foot controller to vary the selected parameter
from 20% to 80% of its total range.
NOTE:
Either or both controllers may be assigned. When both
controllers are used, each can be assigned a different
parameter within the selected effect program.
NOTE:
External control assignments will be lost if a different
memory location is selected without first storing the
assigned effect program into one of the user memory
locations (51 – 99) using the STORE function.
NOTE:
MIDI control change messages received via the MIDI IN
connector can also be used to control assigned parameters.
See "MIDI CTRL ASSIGN" on page 29.
CAUTION!
When setting the range and storing it in the program.
always make sure the preset values for the assigned
parameters are included within the set range.
When setting the range, confirm the values for MIN and
MAX with the controller, and always make sure the preset
values are inside the externally set values.
If the preset values are outside the specified range, there
may be no response to the controller when a recall operation
is carried out.
