Let's say you have 3 or 4 different kind of mixes of the same track/project (vocal up, vocal down, drums up,...).
Each Mix has his own volume, pan, eq settings and so on.
I'd love to save those settings to a slot "A" and continue mixing, so the first mix is not lost and can be recalled emidiately.
When the second mix is finished, you'd simply save it in slot "B" ...and name it "VOCAL UP MIX" or whatever.
Think of it like of a parallel universe.
You have exactly the same arrangement of clips, but there is another layer of effect settings which can be switched to.
