554 Chapter 23 Adjusting the Tempo of Audio Regions
To convert a selected audio region into an Apple Loop, please use either of the
following options:
m Choose Region > Add to Apple Loops Library in the Arrange area.
This method sets transients that are based on the project’s tempo information. For
more details, see “
Creating Apple Loops in Logic Express ” on page 640.
m Choose Audio > Open in Apple Loops Utility in the Arrange area.
This functionality allows you to set the transients manually—independent of the
project tempo. More information can be found in “
Creating Apple Loops in the Apple
Loops Utility ” on page 642).
Setting the Project Tempo to Match an Audio Region
You can adjust your project’s tempo to match the tempo of an audio region. The length
of the region remains constant, but the sequencer tempo is varied automatically.
Imagine you have imported a drum loop that is exactly one bar long, but you don’t
know the drum loop’s tempo. When added to the Arrange area, and the project tempo
does not match that of the drum loop, you’ll see that the drum loop is shorter or longer
than one bar. You can use the Adjust Tempo using Region Length command to set the
project tempo to match that of the audio loop
To match the project tempo to an audio region:
1 Select the audio region that you want to match the project tempo to, in the Arrange
area.
2 Create a cycle in the Bar ruler.
This should closely match the length of the region—usually to the nearest bar.
