Well, that is exactly how I was told to save when I had RT's in the song. I guess what my problem will be then, is most of the stuff I work on is not done when I have to save and go to bed or whatever. So I may re-open at a later time and indeed want to "change things around" some more. What is the best way to handle songs that are going to be in various stages of completion for say , a week. I want to save all the things I have tweaked, of course , so I don't have to start totally over with the mixing and such. That is one reason I haven't saved as a WAV early on, because I still want to separate everything out upon re-open, and continue editing.
