I’ve recently made a new addition to my Sounds Project, and its so simple I can’t believe it took me so long to think of it. The project folder now contains a Sounds Set:

Every time I sit down to do some sampling or sound design, I do it in this set. The format of the set itself is irrelevant: I Just add tracks as necessary and play. If I come up with something I think I’ll reuse, it can be exported to another folder in the Sounds project, but in the meantime all of my current experiments are neatly contained in a single Set.
