The Properties Window for a curve in a Parameter Control Track is shown in the following figure.
When multiple selected curves have different properties, these properties are displayed as broken lines, except for check boxes, which are gray if some selected curves have the property selected and others do not. Any changes made in properties apply to all selected curves.
Use the settings in this window to adjust the following properties of the selected curves:
The start time, end time, and duration, expressed as a combination of bar, beat, grid, and tick values. The last column is expressed in milliseconds rather than ticks if the track is set to play in clock time on the Flags Tab.
If you edit the start time, the duration remains unchanged, and the end time adjusts automatically. If you edit the end time, the start time remains unchanged and the duration adjusts automatically. If you edit the duration, the start time remains unchanged, and the end time adjusts automatically.
Value of the controller at the beginning and end of the curve. Intermediate values are determined by the Type (shape) of the curve.
If you select the Start From Current option, the current value for the parameter at the time the curve starts replaces the start value. For example, if another curve in the segment has previously set the parameter to a different value, then that value is used in place of the start value shown in this Properties window.
Shape of the curve. Possible values are Sine, Logarithmic, Exponential, Instant, and Linear.
Click one of these buttons to flip the curve. In some cases this has the effect of changing the value in the Type list.
