Working with Tracks, Busses, and Submixes in the Timeline
The Timeline is arranged sets of horizontal rows—tracks, busses, and submixes. You add
audio to tracks in your project, use busses to create effect sends, and route audio to
physical output channels using submixes.
The tracks in a project appear in the upper part of the Timeline. Busses appear below
tracks, and submixes appear below busses. The Master bus appears below submixes. The
Master bus represents the final mix that will be heard from physical output jacks. It has
a single volume control and no panners or meters. You can apply effects to the Master
bus.
A separator between each set of Timeline rows helps visually distinguish them, and
disclosure triangles on each separator let you show or hide the different sets. Tracks,
busses, and submixes in the Timeline correspond to channel strips in the Mixer. When
you add a track, bus, or submix, adjust its controls, or add effects, the same changes
appear in the corresponding channel strip when you open the Mixer.
Tracks, busses, and submixes are described in greater detail in Tracks, Busses, Submixes,
and the Master Bus .
