Note: The Follow Tempo option does not create an <strong>Apple</strong> Loops file. <strong>Apple</strong> Loops follow<br />

chord changes; if you record a solo over an arrangement consisting of <strong>Apple</strong> Loops with<br />

transposition changes over time, you might want to select Follow Tempo for your solo,<br />

but you won’t be happy with the double transpositions that will occur.<br />

You also have the option of converting imported audio to <strong>Apple</strong> Loops.<br />

To convert a selected audio region into an <strong>Apple</strong> Loops file<br />

Do one of the following:<br />

µ Choose Region > Add to <strong>Apple</strong> Loops <strong>Library</strong> in the Arrange area.<br />

This method sets transients that are based on the project’s tempo information.<br />

µ Choose Audio > Open in <strong>Apple</strong> Loops Utility in the Arrange area.<br />

This method allows you to set the transients manually—independent of the project<br />

tempo.<br />

For more information about creating <strong>Apple</strong> Loops, see Creating <strong>Apple</strong> Loops in <strong>Logic</strong> <strong>Pro</strong><br />

and Creating <strong>Apple</strong> Loops in the <strong>Apple</strong> Loops Utility.<br />

Setting the <strong>Pro</strong>ject Tempo to Match an Audio Region<br />

You can adjust your project’s tempo to match the tempo of an audio region. The length<br />

of the region remains constant, but the project tempo is varied automatically.<br />

Imagine you have imported a drum loop that does not match your project tempo.<br />

Originally one-bar long, the drum loop adapts to your project tempo, becoming shorter<br />

or longer than one bar. You can use the Adjust Tempo using Region Length and Locators<br />

command to set the project tempo to match the original tempo of the drum loop.<br />

To match the project tempo to an audio region<br />

1 Select the audio region that you want to match the project tempo to, in the Arrange area.<br />

2 Control-click (or right-click) the Cycle button in the Transport bar, and make sure the Auto<br />

Set Locators by Region Selection option is not selected.<br />

3 Set the left and right locator positions in the Bar ruler.<br />
