Control-clicking an inactive solo switch makes an Audio Object “solo safe”. This prevents
it from being muted when you solo another channel. “Solo safe” status is indicated by
an X on the solo button. A second Control-click defeats the solo safe status.
Mute Button
You can mute any Audio Object by pressing the button marked with an M. Pressing the
button a second time restores the previous level.
Stereo Objects
All Audio Object types (Track, Input, and Output) may be configured as stereo. Logic
uses true stereo tracks, provided that Preferences > Audio > Drivers > Universal Track
Mode (UTM) is activated. This means that Track 2 is unaffected when you configure
Track 1 as stereo. Audio Regions on the tracks of stereo Objects are always dealt with
together, no matter what type of operation being performed. If you open the Sample
Editor, both sides of the stereo pair are shown, and are processed together.
Creating Stereo Objects
To do this, select the desired Object (we’ll use the one named “Audio 1” as an
example—click on its name, at the bottom). Click on the Mono symbol, at the bottom
left of the Object, next to the REC button.
The button will now show two interlinked circles, indicating that it’s a stereo Object.
If you click-hold on this button, you will see a pop-up menu that offers four choices:
Mono: Sets the track to play mono files.
Stereo: Sets the track to play stereo files. These may be either “interleaved” or “split”
stereo files.
Left: If a stereo region is assigned to the track, only the left side will be played. If a
mono file is assigned to the track, it will play normally. In either case, the output of the
track will be mono.
Right: If a stereo region is assigned to the track, only the right side will be played. If a
mono file is assigned to the track, it will play normally. In either case, the output of the
track will be mono.
