28 Creating Apple Loops
You can save both audio and software instrument regions as
Apple Loops in Logic Express.
For audio regions, a default set of transients—based on the projects tempo
information—is automatically created. For more information on this method, see the
following section.
You can also use the Apple Loops Utility to create Apple Loops from audio regions. The
Apple Loops Utility is a companion application to Logic Express that allows you to
manage metadata tags and transients in audio files. The Apple Loops Utility offers
sophisticated tag editing functions for audio files. You can, for example, set the
transients manually—independent of the project tempo (for more information, see
Creating Apple Loops in the Apple Loops Utility on page 642). The Apple Loops Utility
does not allow you to create Software Instrument Apple Loops (SIALs).
Which Tool to Use, and When to Use it?
As mentioned above, Logic Express offers Apple Loop creation facilities, and the
separate Apple Loops Utility also allows you to construct your own Apple Loops.
You have a fairly simple decision path to follow:
 If you want to create an Apple Loop based on an audio file that matches the project
tempo, use the Apple Loop creation utilities available in Logic Express.
 If you want to create a Software Instrument Apple Loop (SIAL), use the Apple Loop
creation utilities available in Logic Express.
 If you want to create a non-looped Apple Loop based on an audio file that does not
match the project tempo, use the Apple Loop creation utilities available in
Logic Express. Non-looping Apple Loops (or one-shots) do not follow the project
tempo and key. This is useful if you want to add discrete, non-musical sounds (such
as sound effects) to the loop library, which should not be altered by the tempo and
key properties.
 If you want to create a looped Apple Loop based on an audio file that does not match
the project tempo, use the Apple Loops Utility.
