Follow Tempo Function

Audio files created in Logic Pro 7.1 can now follow the song tempo (including tempo

changes) and the first key signature set in the Global tracks.

As an example: If you record a bass solo at 100 bpm, you can change the song tempo

to 120 bpm and the bass solo will automatically be played back at the new tempo.

The function works with all audio files that were recorded in, or bounced/exported

from, Logic Pro 7.1. The function only works in the parent song (the song the audio files

were created in). If you drag a file recorded in a given song to another song with the

Finder, the file can not follow the song tempo. Bounced/exported files can only follow

the song tempo, if the “Add resulting files to Audio window” option was enabled in the

Export/Bounce window prior to the bounce/export. Files copied between two songs

retain the ability to follow the song tempo.

The song's tempo information is used to tag the beats in the recording. The function

works best if your audio files match the song tempo as precisely as possible. The longer

your audio files are, the more RAM is required for this functionality to work properly.

If you want your audio files to follow the song tempo and key, you will need to select

the appropriate Audio Region in the Arrange window and enable the Follow Tempo

option in the Region Parameter box. The Follow Tempo option is synchronized for all

Regions that make use of the same audio file.

All audio files that follow the song tempo and first key signature are indicated by the

following symbols in Logic:

Note: The Follow Tempo option does not create an Apple Loop! Remember: Apple

Loops follow chord changes—should you record a solo over an arrangement consisting

of Apple Loops with transposition changes over time, you might want to enable Follow

Tempo for your solo, but you won’t be happy with the double transpositions that will

occur…

To create an Apple Loop, please use either of the following options:

• Choose Region > Add to Apple Loops Library in the Arrange window (also see the

ensuing section). This method sets transients that are based on the song’s tempo

information.

• Choose Audio > Open in Apple Loops Utility in the Arrange window (more

information can be found in the Logic Pro 7 Reference Manual). This functionality

allows you to set the transients manually—independent of the song tempo.
