64 Chapter 1 Using Logic
The Apple Loops that feature the green icon can also be added to audio tracks, where
they behave exactly like their blue icon counterparts. They may further be added to all
Audio Instrument and MIDI tracks. On such tracks, these files they can be edited like
other MIDI Regions, including individual note editing.
Another interesting thing about the green Apple Loops is that if dragged onto a
“blank” Audio Instrument track (one with an empty channel strip), the corresponding
instrument, effect, and input setting are automatically inserted.
Note: The Transpose Global track will only transpose Apple Loops used on audio tracks
by ±36 semitones. This is a designed limitation in Logic, as Apple Loops don’t sound
that great when transposed further. This is also true for the Transpose parameter of the
Region Parameter box.
To add an Apple Loop to your song:
m
Simply drag the desired loop to the appropriate track and desired position.
Apple Loops Utility
The Apple Loops Utility allows you to create your own Apple Loops. Apple Loops are
simply audio loops that include metadata “tags” with your loops. These tags provide
information about the audio recorded in a file.
Logic uses tags in one of two ways:
• to help locate files when using the Search features of Logic’s Loop Browser.
• to provide information that Logic uses when matching the file’s tempo and key to
the project tempo and key, this ensuring the best possible playback quality.
Tagged audio files can also contain information about transients. Transients indicate
where beats occur in the file, and Logic uses these transients to play back audio files at
the highest level of quality. The Apple Loops Utility can detect transients present in an
audio file, and you can use the utility to add markers for additional transients, and
move them to new locations.
If you select a Region in Logic’s Arrange window and choose Audio > Open in Apple
Loops Utility the following window opens:
The Apple Loops Utility window consists of the Tags and Transients panes. The bottom
of the window includes a set of playback controls and file management buttons. The
Apple Loops Utility also includes an Assets drawer, located to the right of the main
window, where you manage open files.
Tags Pane
The Tags pane includes areas for different types of tags. It also includes a set of
playback controls that you can use to listen to an open file.
