Working With Tracks, Busses, and Outputs in the Timeline
The Timeline is arranged into three groups of horizontal rows: tracks, busses, and
outputs. You add audio to tracks in your project, use busses to create and control
submixes, and send audio to physical output channels using outputs. Tracks, busses,
and outputs are described in greater detail in “
Tracks, Busses, and Outputs ” on page 90.
The tracks in a project appear in the upper part of the Timeline. Busses appear below
tracks, and outputs appear below busses. A separator between each group helps
visually distinguish them, and disclosure triangles on each separator let you show or
hide the groups.
Tracks, busses, and outputs in the Timeline correspond to channel strips in the Mixer.
When you add a track, bus, or output, adjust its controls, or add effects, the same
changes appear in the corresponding channel strip when you open the Mixer.

m Choose Multitrack > Add Track (or press Command-T).
m Control-click an open area of the Timeline, then choose Add Track from the
shortcut menu.
m Control-click a track, then choose either Add Track Above or Add Track Below from the
