Yea, I'm mixing in Vegas Pro 9. It's not that widely used in the audio community anymore it would seem, but I love it. I've been using it for about 10 years now. The rhythm guitars are the thing I'm having to give the most attention to so far. Out of a 100% mix, I usually get to 80-90% pretty quick because I've been doing this a pretty long time now and instinct and ears get it down pretty fast, but the last 10-20% I usually slow down and take more time with, nitpicking.
With that in mind, if you want to do some DI tracks, that would be cool if you want to. I have some ampsims I can try on them. If not, it's ok too. I'm doing my best with the existing rhythm tracks. Let me know either way.
