Assignable Controller 1 Amplitude
Control (AC1 AmpCtrl)
Range: 64 — +63
This determines the degree to which As-
signable Controller 1 (AC1) affects the
volume (Amplitude) for each Part. For
maximum effect, this should be set to one
of the extreme values, negative or posi-
tive. A setting of 00 results in no volume
control, even when AC1 is operated (or
control change data is received). Nega-
tive settings affect the volume negatively;
in other words, when the controller is at
the minimum position, control over the
volume is greatest. (The control number
used for AC1 is set in the Assignable
Controller 1 Control Change Number
parameter above.)
NOTE
For more information on using positive and
negative values, see the illustration and hint in
Assignable Controller 1 Filter Control (page
124).
