Changing Track Time Format
By default, tracks use the same time format as the project (Time-based or Beats-based).
You can change the time format of a track, which changes the behavior of tagged clips
when you change the project tempo.
When the track time format is Time-based, clips remain at the same time position (the
same second or frame) when you change the project tempo. When the track time format
is Beats-based, clips remain at the same beat position (the same measure, beat, and beat
division) when you change the project tempo.
When you set a track to Beats-based time format, a metronome appears in the corner of
the track icon.
To change a track’s time format
1 Select the track.
2 Choose Multitrack > Track Time Base, then choose a format from the submenu.
Removing Tracks, Busses, and Submixes
You can remove a track, bus, or submix if you decide you no longer want it in a project.
