Creating Apple Loops
This will export the Apple Loop as a new audio file with all plug-in effect processing of
the track/channel on which the Apple Loop is placed. To export the Apple Loop
without these effects, bypass them before exporting the region.
You should note that although this new file will play at your project’s current tempo
and key, it can’t follow subsequent tempo or key changes like other Apple Loops; such
files are fixed at the project tempo and key—in use when the file was exported.
∏
Tip: If you enable the Follow Tempo option for the audio file, it will follow the project
tempo and the first key signature set in the global tracks. For further information, see

Using the Follow Tempo Function
Apple Loops and Sample Rates
The method used to convert the sample rate of audio files also applies to Apple Loops.
This sample conversion method also includes correction of transient positions.
To convert the sample rate of an Apple Loop:
1
Select the desired Apple Loop in the Audio Bin.
2
Choose Audio File > Copy/Convert File(s) from the local menu (or use corresponding
key command, default: Control-C).
3
Choose the desired sample rate (and all other file conversion settings) in the ensuing
dialog, select the folder location, then click Save.
If the “Change file reference in Bin” option is activated, the sample rate converted Apple
Loop is automatically added to the project. It will follow the project tempo and key
changes (provided that the Key tag was set in the original loop).
Note: If a new Apple Loop is created, it will need to be indexed to make it visible in the
Loop Browser. Loops can reside in any directory, but you need to tell Logic Express
where to find them.
You will probably not need to convert Apple Loops as often as standard audio files
when working with Logic Express, as Apple Loops offer a major advantage: If the
sample rate of your project is changed, the playback speed of all Apple Loops currently
used in the project will automatically be adapted to the newly selected sample rate.
