PERFORMANCE EDIT MODE / 3: Full Edit. 3-1: Layer
Min (Minimum parameter value)
Range: 0 ... 100
Sets the lower limit of the control range. A setting of "0", for example,
means that when the lowest control change value is received the assigned
parameter will also be set to its lowest value. A setting of "50" means that the
lowest control change value 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).
Max (Maximum parameter value)
Range: 0 ... 100
Sets the upper limit of the control range. A setting of "100", for example,
means that when the highest control change value is received the assigned
parameter will also be set to its highest value. A setting of "80" means that the
highest control change value will set the assigned parameter to about 80% of
its range (a parameter with a range of 0 to 127, for example, would be set to
about 102).
