Solo Safe Mode

Pro Tools lets you solo safe a track. This prevents the track from being muted even if you solo other tracks. This feature is useful for tracks such as Auxiliary Inputs that are being used as a submix of audio tracks, or effects returns, allowing the audio or effects track to remain in a mix even when other tracks are soloed. It is also useful to solo safe MIDI tracks so that their playback is not affected when you solo audio tracks.

AFL or PFL soloed tracks (Pro Tools HD only) cannot be solo safed.

To solo safe a track:

Control-click (Windows) or Command-click (Mac) the Solo button on the track. This prevents the track from being muted even if you solo other tracks. The Solo button changes to a transparent color in Solo Safe mode.

To return a solo safe track to normal:

Control-click (Windows) or Command-click (Mac) the Solo button on the track again.
