Once you have added your audio and MIDI regions to the Arrange area, you can edit and reorganize them to create an overall arrangement, or project. Most arranging and editing techniques work identically for both audio and MIDI regions. Apple Loops are also handled in a similar fashion. Where handling differs, variations are pointed out in the appropriate sections of this chapter. Note that all operations described with a pluralized heading (regions, for example), apply to one or more selected region(s).
