Soloing When the Track Solo Buttons Are Hidden
If the Track Solo buttons are hidden—to save space—you can still solo a track with the
Solo button on the Transport bar.
To solo a track when the Track Solo buttons are hidden
µ
Click the Solo button on the Transport bar, then click the track.
Soloing Multiple Tracks in the Arrange Area
It is possible to solo multiple tracks at one time.
To solo multiple tracks
Do one of the following:
µ
Click and hold a Track Solo button, then drag the pointer up or down.
The Solo buttons of all swiped tracks switch to the same state.
µ
Hold down the Shift key while the Transport Solo button is active, then click the desired
track names.
Record-Enabling Tracks in the Arrange Area
You can use a track’s Record Enable button to arm a track for recording. For more
information, see
Recording in Logic Pro .
Freezing Tracks in the Arrange Area
The Freeze function saves almost 100 percent of the CPU power required for software
instrument and effect plug-in calculations. You can individually freeze audio or software
instrument tracks, except when working with multi-output instruments (Ultrabeat, for
example). In this case, the Freeze function is not available.
Understanding the Freeze Function
Internally, Freeze performs individual offline bounce processes for each frozen track. All
plug-ins of a track (including software instrument plug-ins, if applicable, along with all
related automation data) are rendered into a freeze file.
As long as a track is frozen—following the freeze process—the freeze file will play back
in place of the original track (and its CPU-hungry plug-ins). The original track and plug-ins
are temporarily deactivated, and use no CPU resources.
