Grouping Files in the Audio Bin
You can group audio files together, making handling of large numbers of files easier and
faster. In the following image, you see a Guitars and Vocals group, with several files in
each.

Separating files into categories simplifies handling, particularly if all files are similarly
named. For example, audio imported from another application may be named “audio01,”
“audio02,” “audio03,” and so on, regardless of whether a vocal, guitar, or drum part. When
creating a large arrangement, grouping files into categories can be a life-saver.
