Audio Files and Regions

arrangement.

Edit > Select unused selects all audio files and Regions that are not used in the current
song arrangement. You can use this function at the end of a session or production, to

Audio Window Groups
You can “group” audio files together, making handling of large numbers of files easier
and faster. In the image, you’ll see a Guitars and Vocals group, with several files in each.
This separation simplifies handling, particularly if all files are similarly named. As
examples, audio imported from another application may be named audio01, audio02,
audio03, and so on, regardless of whether a vocal, guitar, or drum part.
