I'm trying to figure out a better workflow for designing more complex effects with multiple layers of heavily-processed sounds. So far I've just been using AudioSuite for processing or, if I have to automate a plug-in, I put it in an insert and then print it. All in my FX session. This works, but it's not a very fluid workflow and makes it hard to change things after the fact; if I use AudioSuite, I'll have to remember/store somehow what settings I used, go back to the unprocessed version and process it again; if I use dedicated tracks for each composite effect with inserts, I retain all the plug-in settings but end up with a huge number of tracks.
So I'm curious to hear what you guys do. Do you have a dedicated session for each effect, or one big master session, do you save plug-in settings so you can come back to them later, or do you just forget about it?
