Tagging Multiple Files
When multiple files are selected, only the tags that apply to all the selected files can be
changed. Items in the Tags tab that do not apply to all the currently selected files are
dimmed and unavailable.
Each tag has a checkbox. Select the checkbox next to the tags for which you want to
save changes.
To tag multiple files:
1 Select the files in one of the following ways:
 Shift-click to select adjacent files in the Assets drawer.
 Command-click to select nonadjacent files in the Assets drawer.
 Press Command-Shift-A to select all files in the Assets drawer.
2 Make the changes you want to the available tags for the selected files in the Tags tab.
See “ Tags Tab ” on page 265 for information about the options in the Tags tab.
3 Select the checkboxes next to the tags for which you want to save changes.
4 Click Save to save changes to the selected files, or click Save All to save all changes.
There are many keyboard shortcuts to simplify the task of tagging files. For a complete
list of keyboard shortcuts, see “
Apple Loops Utility Keyboard Shortcuts ” on page 275.
Working With Transients
Transients are the points in an audio file where beats occur. Typically, transients occur
at the widest areas of a waveform in the waveform display. During playback,
Soundtrack Pro adjusts looping files using a technique called stretching to achieve the
best audio quality, based on the loop’s transients. Non-looping files are not affected by
stretching.
When you open a file in Apple Loops Utility, it looks for transients at every 16th note
position, based on the file’s tags for tempo and the number of beats. You can change
the beat value at which Apple Loops Utility detects transients using the Transient
Division pop-up menu.
To display a file in the Transients tab:
m Select the file in the Assets drawer, then click the Transients tab.
The Transients window can display only one file. If multiple files are selected, no
waveform is displayed in the window. The waveform display in the Transients tab
displays both the transients detected by Apple Loops Utility and transients you add to
the file. You can add transients and move existing transients in the Transients tab.
To add a new transient:
m Click in the darker area above the Beat ruler in the waveform display.
