Backwoods - I'm trying that workflow. It is pretty cool to use a separate program. When I master - I generally make a separate Sonar Project and load all the mixdowns into separate audio tracks. Then apply the mastering chain to each track individually. I find that provides the same level of productive value and keeps me from going back constantly adjusting the mix when I should be focusing on mastering. Since I've started doing that, I focus more on getting the mix right before I even start mastering, etc.
Soundblend - Got revival this morning. I'll have to play around with it. Thanks for the tip.
