To get a feel for how Apple Loops work, let's add one to the arrangement.
From this book's companion DVD files, open the project file named 05Begin.lso (in the Lesson 5 Project Files folder), or continue working on your song from the previous lesson.
Open a Finder window over Logic.
To open a Finder window over Logic, click the Finder icon in the Dock. If any windows are open in the Finder, they will pop to the surface. If no windows are open in the Finder, a new one will pop open.
From this book's companion files, navigate to the Lesson 5 Project Files > Apple Loops folder.
In that folder is an Apple Loop named Bongo Groove 05.aif.
Drag the Bongo Groove 05.aif Apple Loop from the Finder window, and drop it into the track named Audio 4 at 1 1 1 1.
The Apple Loop is added to the song. Notice that the Apple Loop automatically fills one bar of the song at the current tempo. Additionally, check out the Apple Loop icon to the right of the new Audio Region's namethat little loop-the-loop is a good visual indicator to help you spot Apple Loops in your arrangement.
Mono Apple Loops have one loop-the-loop, while stereo Apple Loops have two.
Press the spacebar to start the playback.
Change the tempo of the song from 110 to 126.
As you can hear, the Apple Loop adjusts its tempo and plays in time with your song. How cool is that?
Using the Apple Loops Utility
Logic comes with the Apple Loops Utility. With it, you can turn any AIFF, WAV, or SDII file into ready-to-use Apple Loops. In many cases, it takes more time to use Logic's internal pitch-converting and time-stretching functions to fit a loop into your song than it does to open the Apple Loops Utility and transform the normal audio loop into an Apple Loop. And once the loop is converted, it will always stay in time with your song, even if you need to make an unexpected tempo change later.
The Apple Loops Utility
As it turns out, creating Apple Loops is even easier than you might expect. Just add the audio loop you want to convert to your arrangement and select it. Then, from the Arrange window's local menus, choose Audio > Open in Apple Loops Utility, as shown. Converting normal loops couldn't be any easier.
