A Key Number Curve can be applied to any Effect Parameter Controller. Such a Curve defines a value to be added to the current Controller value as a function of Key Number. Such Curves are often used to "voice" a Parameter by adjusting its value as a function of Key Number.
Key Number Curve Editor (left panel)
The Key Number Curve display shows a graph of the Modified Controller Value versus Key Number
The Modified Controller Value is the sum of the Key Number Curve itself and the current Controller value. Thus, a zero Key Number Curve is displayed as a constant graph equal to the current Controller value. When you change the current value of the Controller using the Slider in the right panel, the displayed Curve will move up and down with it, corresponding to no change in the Key Number Curve itself.
Pressing the Smooth Button applies a smoothing filter to the Key Number Curve
The Reset Button resets the Key Number curve to zero, resulting in a constant graph equal to the current Controller value
