Freeze tracks in Logic Pro for iPad
You can freeze a track, reducing its processor usage to that of a high-resolution audio track without effect plug-ins, regardless of the number or complexity of the plug-ins actually used on the track. Freezing is particularly useful for software instrument tracks and for audio tracks that use complex effects. It is not available for multi-output software instruments.
When you freeze a track, the track is bounced to an audio freeze file, which includes the output of any plug-ins on the track and any track automation. While the track is frozen, the freeze file plays back in place of the original track, which is temporarily deactivated (including its plug-ins). You can still use track controls (such as mute and solo), but you can't edit track content (including region mute or solo, for example).
If you want to edit the track, you can unfreeze it, make the changes, and then freeze the track again.
Freeze is designed to circumvent CPU-intensive processes, such as complex software instruments and complex plug-ins (such as reverbs, filter banks, or Fourier transform–based effects). If your iPad can calculate all active processes in real time, freezing tracks is unnecessary. Freezing tracks is recommended when tracks with CPU-intensive software instrument or effect plug-ins are in a finalized state, requiring no further changes. Freezing also helps to free memory in low-memory situations, such as when using memory-intensive software instruments.
You can also have Logic Pro automatically freeze tracks if the iPad can’t process the audio in time. See General Audio settings in Logic Pro for iPad.
Freeze a track
In Logic Pro, select the track, then show the track controls.
Tap the Freeze button
in the track header.Tap the Inspector button
.In the inspector, tap the disclosure arrow for the More section.
Tap the Freeze Mode menu, then choose the Freeze mode:
Source Only: Freezes the track signal without any effect plug-ins. When selected, the Freeze button appears green. This Freeze mode is useful when using processor-intensive software instruments.
Pre Fader: Freezes the track signal including all effect plug-ins. When selected, the Freeze button appears blue.
Tap the Play button
in the control bar to trigger freezing. Tap it again to start playback.To unfreeze the track, tap the Freeze button again.
If the Freeze button does not appear in the track headers, customize the track headers so that it is visible.
