200 Chapter 9 Working With Tracks
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.
Simply press the Transport Solo button, and click on the desired track.
Soloing Multiple Tracks
If you hold down Shift while the Transport Solo button is active, and click on the
desired track names, you will solo them (when the track Solo buttons are hidden).
If you hold any modifier (except Control) while clicking on a Solo button in the track
list, all tracks in the currently-selected display level are soloed. If they were already
soloed, they will be unsoloed.
You can also click-hold the Solo button of one track, and drag the mouse up or down.
The Solo buttons of all swiped tracks will switch to the same state.
Record-Enabling Tracks
You can use a track’s Record Enable button to arm a track for recording. For more
information about enabling tracks for recording, see Chapter 14, “
Recording in
Logic Pro ,” on page 351.
Freezing Tracks
The Freeze function saves almost 100% of the CPU power required for software
instrument and effect plug-in calculations. You can individually freeze audio or software
instrument tracks.
About 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.
∏
Tip: The Freeze facility also works with DSP hardware such as the PowerCore,
LiquidMix, Duende, and UAD devices. This enables you to combine Logic Pro
instruments and effects with those provided by the DSP hardware—even if the
processing capacity of your computer, the DSP hardware, or both, are exceeded.
