74 Chapter 1 Using Logic

• Clicking on the arrow in any selected column title will sort the list in ascending or

descending alphabetical, tempo, key, beat, or favorite order.

• Columns can be resized by dragging the vertical lines between column titles.

• Selection of any entry in the list of files will automatically begin playback. You can

stop playback by clicking on the speaker icon in the left-hand column.

There are two types of Apple Loops: those featuring a blue sound wave icon and

others with a green note icon. The Apple Loops that feature the blue icon can be

added to audio tracks, and can be edited like other Audio Regions. These files have the

major advantage of automatic tempo and key matching to that of the song tempo and

key.

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:

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.
