Assignable Controller 1 Filter Control (AC1 FilCtrl)
This determines the degree to which Assignable Controller 1 (AC1) af-
fects the Cuttoff Frequency of the Low Pass Filter for each Part. For
maximum effect, this should be set to one of the extreme values, nega-
tive or positive. A setting of 00 results in no control over the Filter,
even when AC1 is operated (or control change data is received). Nega-
tive settings affect the Filter negatively; in other words, when the con-
troller is at the minimum position, control over the Filter is greatest.
(The control number used for AC1 is set in the Assignable Controller 1
Control Change Number parameter above.)

Positive and negative values can be most effectively used by setting two different Parts to
opposite settings. In this way, moving the controller (for example, a foot controller) one way
will affect one Part and moving it the opposite way will affect the other Part.
