Apple Logic Pro 9 - Manual (Page 851)

You can use one of the following options to ensure that loops created from software
instrument regions will sound the same as the original regions:
• Drag your SIAL (the original of which was assigned to bus sends) to an audio track
instead of an instrument track. When you create a software instrument loop, the audio
file that is rendered will include any bus processing. This will sound identical to the
original.
• When creating a loop from a software instrument region, you should directly insert all
effects needed to reproduce the desired sound into the instrument’s channel strip. This
will allow all sound elements to be faithfully re-created when you add the loop to an
instrument track.
• When using SIALs on an unassigned channel strip, manually set up the sends and bus
effects needed to reproduce the sound of the original region.
Reindexing the Apple Loops User Library
There may be occasions when you need to reindex your Apple Loops user library—after
you move loops from the User Loops folder to another hard disk, for example.
To reindex the Apple Loops user library
µ
Control-click (or right-click) the Loop Browser’s search results area, then choose Reindex
Apple Loops User Library from the shortcut menu.
Creating Apple Loops in the Apple Loops Utility
The Apple Loops Utility provides sophisticated functions for creating Apple Loops from
audio regions. It can detect transients present in an audio file, and you can add markers
for additional transients. You can also move these transient markers to new locations.
To create an Apple Loops file in the Apple Loops Utility
1 Select an audio region in the Arrange area.
2 Choose Audio > Open in Apple Loops Utility from the local Arrange menu (or use the
corresponding key command).
If the length of your audio file does not match the bars or beats, the following dialog
appears:
