Curve Mapping

A Curve Mapping can be applied to any Effect Parameter Controller. Such a Curve maps each input Controller value a new value. Such Curves are often used to adjust a Slider somewhere between Linear and Log or Exponential response.

Curve Mapping Editor (right panel)


The Curve Mapping display shows a graph of the Modified Controller Value versus Controller Value

The Modified Controller Value is the mapping of the current input Controller value according to the Key Number Curve. Thus, the identity Key Number Curve (no change) appears as a 45-degree line.
