Add Apple Loops to your projects in Logic Pro for Mac
After searching for loops in the Loop Browser and finding the ones you want to use, you add them to your project. In the Tracks area, you can move, copy, and make other changes to the loops.
New projects default to a project tempo of 120 bpm and a key of C major. If the first content added to a project is an Apple Loop (meaning, before any audio or MIDI have been added or recorded to the project), the project tempo and key are adjusted to match the Apple Loop. When a project already contains content (either by recording directly into the project or adding content), Apple Loops automatically match the current project tempo and key on the Signature track at the position where you place the loop. If you subsequently change the project tempo, Apple Loops automatically conform to the new tempo. If you create key changes on the Signature track, the regions created from the loops follow the key changes and are transposed to the new key. See Transposition and the Pitch Source parameter.
