Chapter 8 Using Apple Loops 65
Note: The Apple Loops Utility does not allow you to create SIALs.
Which tool to use, and when to use it?
As mentioned above, Logic Pro offers Apple Loops 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 from an audio file that matches the song tempo,
use the Apple Loop creation utilities available in Logic Pro.
 If you want to create a Software Instrument Apple Loop (SIAL), use the Apple Loop
creation utilities available in Logic Pro.
 If you want to create a non-looped Apple Loop from an audio file that does not
match the song tempo, use the Apple Loop creation utilities available in Logic Pro.
Non-looping Apple Loops (or one-shots) do not follow the song 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 from an audio file that does not match the
song tempo, use the Apple Loops Utility.
Read the following section if you want to create Apple Loops in Logic. Information on
“Creating Apple Loops in the Apple Loops Utility” can be found on page 68.
Creating Apple Loops in Logic
When you save a Region as Apple Loop in Logic Pro, the Region is added to the loop
library and appears in the Loop Browser, allowing its use in other songs.
The tempo information of the song is used to tag the transients of user-created Apple
Loops. This function works best if your audio files match the song tempo as precisely as
possible.
Note: User-created Apple Loops behave exactly like the Apple Loops that ship with
Logic, GarageBand and Jam Packs: They follow the tempo of your song and match the
song key (as defined by the initial key signature). Apple Loops will also follow any
chord transpositions in the Chord track. For further information, see the section on the
“Chord Track” on page 78.
To create an Apple Loop in Logic:
1 Select the Audio or Audio Instrument Region in the Arrange window.
2 Choose Region > Add to Apple Loops Library in the local Arrange menu.
3 In the Add Region to Apple Loops Library dialog:
 Type in a name for the loop, choose the scale, genre, instrument category,
instrument name and appropriate mood descriptions—to simplify searches.
