Automation time base

You can specify what happens to existing automation envelopes when you change the project’s tempo. Automation can be locked to absolute time or musical time. You specify the automation time base in the Track Properties Inspector’s Automation section. The two Time Base options are as follows:

Musical (M:B:T). If the track is set to the Musical time base, the automation’s M:B:T position stays constant, and its Absolute position shifts.

Absolute. If the track is set to the Absolute time base, its Absolute position stays constant, and its M:B:T position shifts.

To specify a track’s automation time base

1.	Click the track or bus you want to show in the Track Inspector.

2.	Click the Show/Hide Track Properties button at the top of the Inspector pane, or press CTRL+SHIFT+I.

3.	In the Track Properties Inspector’s Automation section, click the Time Base item and select Musical (M:B:T) or Absolute.
