188 Chapter 5 Working in the Timeline
Working with Tagged and Looping Clips
Soundtrack Pro includes a large selection of Apple Loops that you can use to add Foley
effects, background ambience, sound effects, and music transitions to your projects. Apple
Loops tagged as looping files automatically match the tempo and key of the project.
Transposing Tagged Audio Clips
When you drag an audio file tagged with key information to the Timeline,
Soundtrack Pro transposes the clip to the project key. You can transpose tagged clips to
another key to create chord progressions from the same audio file or to achieve other
musical effects. You can transpose a tagged clip to any interval from one octave above
(+12 semitones) to one octave below (–12 semitones) its current key.
Note: Soundtrack Pro uses the key tag in the audio file to transpose it. In order to be
correctly transposed, the file must be tagged.
To transpose a tagged audio clip, do one of the following:
m Select the clip, choose Clip > Transpose, then choose the number of semitones by
which you want to transpose the clip up or down.
m Select the clip, open the Details tab, then use the Transpose pop-up menu to choose
the number of semitones by which you want to transpose the clip up or down.
Changing a Clip’s Playback Mode
Audio files you add to the Timeline can be either looping or non-looping. Looping files
are special audio files that can be used to create repeating patterns, and include
musical phrases useful for creating music beds. Audio files containing discrete,
non-rhythmic sounds, sound effects, and other non-musical sounds such as dialogue or
sound effects should be used as non-looping files in most cases.
When you add an audio file to the Timeline, the audio file is added as a clip with
non-looping playback mode unless the audio file is tagged as a looping file. You can
change the playback mode of a clip after you add it to the Timeline.
To convert the playback mode to looping, do one of the following:
m Select the clip, then choose Clip > Convert to Looping.
m Control-click the clip in the Timeline, then choose Convert to Looping from the
shortcut menu.
To convert the playback mode to non-looping, do one of the following:
m Select the clip, then choose Clip > Convert to Non-Looping.
m Control-click the clip in the Timeline, then choose Convert to Non-looping from the
shortcut menu.
