noob to audio here ... before I started a new thread, I want to ask in case this "cue" thing is my answer ..... If I am saving a file as PCM Wave ... is there any way to save it so if I open it later, I can undo an edit should I choose to do so? I checked through a LOT of FAQ's and haven't found an answer yet. I understand destructive editing to be where you can't undo? But I can't imagine someone working on a very lengthy project and not being able to reopen it the next day or week or whenever and not being able to change a former edit? e.g. I apply some reverb to a portion of the file and after saving and closing and coming back another day, am I able to undo that effect or alter it?

Thanks and if saving "cues" is not part of the answer to this question, I'll start a separate thread unless someone is able to point me to an existing one.
