Set
The "Set" command allows MSC to control potentiometers using both a numeric control number
(which specifies the potentiometer) and a data field (which controls the level: 0-100). Control values
are as follows:
Control
Value
1-127
128
129
510
Accompanying any of these indications in the MSC data, a numeric value of 0-100 would set the
specified potentiometer to that level.
All other control values are ignored.
F i r e
This command fires a macro. MSC supports macros 1 through 127 only. Therefore a numeric value
of 1 - 127 would accompany this command.
