I don't think you can do that in GarageBand.
Logic has a neat feature where it adds metadata to the aiff file when bouncing a song. It embeds the Tempo and Markers of you project in the aiff file. When you import that file into another Logic projects, it asked you if you want to import that data. This way you could add your notes as Markers in your project (similar to GarageBand's Arrange Region) and that text will be carried with the bounced aiff file.Hope that helpsEdgar Rothermich
