I don't know if you mix for a living or not, but I do.
I certainly hope that my mixes have improved over the years due do my personal advances as well as my accesss to better gear and studios.
For example, the original Chronic album was largely tracked and mixed on an SSL 4056 E series console, not exactly known for its punch or warmth. Yet, that signature Dre sound is there. Most 'Top-Gun" mixers have prep guys that set up the gear and patches, clean up any stray audio in the tracks, etc.. and even get basic levels. Sometimes you will see this person credited as "mix engineer". I have been credited as such when I would spend hours getting everything setup and even EQed to MY liking, to have the mixer come in at the end of the evening to modify what I'd done, get his own levels and rides and do his drops.
Dre has a crew of engineers that he works with. It's no big secret. There is an article from EQ magazine from a few years ago that maps out the roles of Dre's staff. Everyone is credited for their contribution, including "Vito", Mike E, Big Bass Brian, and even Scott Storch. Why don't you look that up, and while you are at it, find the issue of Scratch Magazine from about 6 months ago. It gives an excellent glimpse of behind-the-scenes Dre.
What offends me is this insinuation that someone else "mixes for Dre" as you named this thread when you began it, and the suggestion that he puts his name on other people's work. I think it is irresponsible to post somthing like that in a public forum, unless YOU PERSONALLY did a mix 'for Dre" and did not receive credit for it. For some reason, I doubt that is the case.
