The pop-up menu at the top of the Track List provides commands that allow you to show or hide all tracks, tracks currently selected on-screen, or specific types of tracks (audio, Auxiliary Input, Master Fader, MIDI, Instrument, VCA Master, or Inactive tracks).
The Sort Tracks By command lets you set the track order according to
Name,
Type,
Edit Group,
Mix Group, or
Voice. The sort order will be reflected in the Track List in the Mix, Edit, MIDI Editor, and Score Editor windows.
When a track that is a member of an active group is hidden from view, editing operations performed on other members of the group in the Edit window will not affect the hidden track. In the Mix window, however, all operations other than record-enable will affect a hidden track that is a member of an active group.
The options in the Track List menu in the Score Editor window are different from the Mix, Edit, and MIDI Editor windows. For more information, see
Track List.
