Viewing Automation
For more information, see the following topics:
Pro Tools creates a separate playlist in the Edit window for each type of automation in a track, including a playlist for each type of Trim automation. This data can be viewed and edited in the same way as audio and MIDI data. You can either change Track Views to show the automation you want, or you can reveal an Automation lane under the track regardless of its Track View.
