Using the Time Compression/Expansion Trim
Tool in Grid Mode
The Time Compression/Expansion Trim tool
can be used in Grid mode to match a region to
the tempo of a session or a section of a session.
For example, you might import a one-bar drum
loop with a tempo of 90 BPM into a session with
a tempo of 120 BPM. In Grid mode, you can use
this tool to simply and quickly "time compress"
the drum loop to the length of one measure,
with minimal loss of audio fidelity.
Trimming regions while in Relative Grid
mode will trim the regions in grid incre-
ments while maintaining their relative off-
set (if any) from the grid.
To use the Time Compression/Expansion Trim tool
in Grid mode:
Set the Edit mode to Grid.
