Let's say I open audition and import 20 sound files and begin working with them in Edit view. At some point I would like to close Audition, open it up again at a later time, and have those 20 files appear for me to work with without re-importing them (or at least one step method of bringing them back in without having to go out to multiple folders and import them in again).
Is this possible under Edit View?
No, not as far as I am aware.
The only workaround I've come up with is creating a dummy session under multitrack view, dropping in these 20 files, and then saving the session.
That's what you'll need to do. You can then easily flip back to the edit view to edit the files.
If you are worried that this will interfere with the layering and arrangement you do in the multitrack view, you can always mute the "holding" tracks containing the files that you haven't edited yet.
