MC3 or MC4 PARAMETER LIST (40 ... 75)
Range: 0 ... 100
Sets the lower limit of the MIDI controller 3 or 4 range. A setting of "0",
for example, means that when MIDI controller 3 or 4 is set to its minimum
position the assigned parameter will also be set to its lowest value. A setting of
"50" means that the lowest controller position will set the assigned parameter
to about 50% of its range (a parameter with a range of 0 to 127, for example,
would be set to about 63).
Range: 0 ... 100
Sets the upper limit of the MIDI controller 3 or 4 range. A setting of
"100", for example, means that when MIDI controller 3 or 4 is set to its maxi-
mum position the assigned parameter will also be set to its highest value.
A setting of "80" means that the highest controller position will set the as-
signed parameter to about 80% of its range (a parameter with a range of 0 to
127, for example, would be set to about 102).
