Apple Soundtrack Pro 3 - Manual (Page 367)

Automation offers a powerful way to add drama and interest to your projects. You can
automate volume and pan changes to tracks, busses, and submixes and automate changes
to effect and effect send parameters in multitrack projects. You can also automate volume,
pan, and effects changes in audio file projects.
In Soundtrack Pro, you can manipulate automation manually, or record changes and
movements made in either the application itself, or on a control surface. You can manually
add and adjust envelope points on envelopes in the Timeline and in the File Editor. You
can record changes over time to sliders, faders, and other controls in the Timeline, the
Mixer, and the Effects tab. You can also record movements with faders on a control surface
connected to your computer and mapped to Soundtrack Pro commands and functions.
This chapter covers the following:
• Working with Envelopes (p. 367)
• Recording Automation Data (p. 376)
Working with Envelopes
In the Timeline, each track, bus, and submix has a set of envelopes. The envelopes appear
as horizontal lines stretching across the length of the project directly below the track,
bus, or submix. You adjust an envelope by adding envelope points and moving the
envelope points to new values at different points in the Timeline.
For video editors accustomed to working in Final Cut Pro, envelopes provide the same
type of functionality as keyframes. The difference is that you can edit envelopes at a finer
level of precision than you can using keyframes, allowing extremely powerful control
over automated changes.
