Track Stacks and the Logic Pro Library
The patches available in the Library vary depending on the Track Stack type, and which
track in the Track Stack is selected:
When the main track of a folder stack is selected, no patches are available in the
Library, and patches can’t be saved.
When the main track of a summing stack is selected, patches of all underlying channel
strip types (software instrument, audio) are available in the Library.
For both types of stacks, when a subtrack is selected, patches for the appropriate track
type are available.
If you choose a Track Stack patch when a subtrack of a folder stack is selected, the
entire Track Stack is loaded into the folder stack.
Control timing with the groove track in Logic Pro
You can set a track as a groove track, and match (synchronize) the timing of other tracks in
the project to it. When you play the project, the timing of matched tracks adjusts to match
the timing of the groove track.
Only one track in a project can be a groove track. You can select which tracks in the
project match the timing of the groove track. When a track is set to match the groove
track, time quantization is unavailable for that track.
Set the groove track
1. In Logic Pro, hold the pointer over the left edge of the header of the track you want to
set as the groove track.
If the groove track is not available, you can show it or configure track header
components so that it is visible.
2. Click the star that appears in the narrow rectangle on the left edge of the track header.
