To help you keep track of the current timeline organization, a diamond-shaped change
indicator appears in the Index button in the top-left corner of the timeline whenever you
change any roles settings from their default states. These roles changes include showing
roles and subroles in separate audio lanes, focusing the timeline on a specific role, and
turning off roles or subroles.
Note: You can also customize the display of clips in the timeline by changing the clip
appearance and height, and you can choose whether to view clips by name or role. See
Adjust timeline clip appearance in Final Cut Pro.
Edit components in audio lanes in Final Cut Pro
By default, audio clips in the timeline are represented by a single audio waveform. You
can expand the audio portion of any clip to view and edit audio components down to the
individual channel level.
You can also display all audio components in audio lanes, organized by roles and subroles.
This view provides precise control over all the audio elements in your project. The
components remain in their dedicated lanes, even when you trim overlaps. For any lane,
you can switch between the audio component view and the default view with a single click.
