You can solo a track, silencing all tracks that are not also soloed. Soloing tracks is useful when you want to work on a track individually, or work on a few tracks, without hearing the other tracks in the project.
Solo a track
Click the track’s Solo button in the track header.
The Solo button turns yellow, and the Mute buttons of all unsoloed tracks flash blue. Click the button a second time to restore the track to its previous state.
Solo multiple tracks
Do one of the following:
Click-hold a Solo button in a track header, then drag the pointer up or down.
The Solo buttons of all swiped tracks switch to the same state.
Hold down Shift while the Solo button in the control bar is active, then click the names of the tracks you want to solo.
