556 Chapter 23 Adjusting the Tempo of Audio Regions
To adjust the region length to match the locator positions:
1 Set the left and right locator positions.
2 Choose Audio > Adjust Region Length to Locators to stretch or compress the selected
audio region to fit between the locators.
The region start point is not changed by this function—so it doesn’t matter if the
locators are not directly above the region.
To adjust the region length to the nearest bar:
m Choose Audio > Adjust Region Length to Nearest Bar.
This adjusts the length of the selected region to the closest whole bar.
This function is ideal for fitting previously trimmed drum loops into projects where
there is a small tempo discrepancy between loop and project.
Using the Follow Tempo Function
Audio files recorded in Logic Express can follow the project tempo—inclusive of tempo
changes—set in the global tracks.
Note: These audio files can also follow the first key signature set in the global tracks.
For more information, see “Working With Time and Key Signatures” on page 755.
As an example: If you record a bass solo at 100 bpm, you can change the project
tempo to 120 bpm and the bass solo will automatically be played back at the new
tempo.
The function works with all audio files that were recorded in, or bounced/exported
from, Logic Express.
The function only works in the parent project (the project the audio files were created
in). If you drag a file recorded in a given project to another project with the Finder, the
file can not follow the project tempo.
Bounced or exported files can only follow the project tempo if the “Add resulting files
to Audio Bin” option was enabled in the Export or Bounce window—prior to the
bounce or export.
Files copied between two projects retain the ability to follow the project tempo.
The project’s tempo information is used to tag the beats in the recording. The function
works best if your audio files match the project tempo as precisely as possible. The
longer your audio files are, the more RAM is required for this functionality to work
properly.
