Do You Work From Stems?

How do you work with things like parallel compression on drums? Well, you bake it in that thing. You work from stems. Even the stuff that i've mixed in stereo, i go back and open up those mixes. It took forever to figure out how tho key things s and split things out. Soian 14 stems of background vocals and all this kind of thing. That way, that's taken care of. If you get a good set of stems, the only thing you've got to do is kind of recreate the mess that happened in mastring bringing up the stereo mix to whatever level it ended up being.
