Working with Automation
Thinning Envelope Points in Recorded Automation Data
Recording automation data can generate a large number of envelope points. The
number of envelope points recorded can make editing envelopes difficult, and in some
cases affect playback performance.
You can reduce or “thin” the number of envelope points recorded from a control
surface in the Project Preferences. You set the amount of thinning using the
Automation Recording Sensitivity slider. The automation data is thinned when you
finish recording automation.
To set the amount of thinning:
1
Choose Soundtrack Pro > Preferences, then click the General button.
2
In the General pane, drag the Automation Recording Sensitivity slider to adjust the
amount of thinning.
When the slider is set to High, no thinning occurs. The envelope contains every
movement of the control. Dragging the slider to any position other than High results
in some thinning of envelope points. By default, the slider is set to a moderate
amount of thinning.
