I am blaming all of you for making me buy it. Its all your faults.

I didn't like Mixbus 2 but 3 seems a lot better and somewhat sophisticated. It does sound better. I was impressed by how well it sounds. I believe one can get the same sound from Sonar but with a lot more fuss.
One area that is a real problem is its VST support. I found a lot of my goto VSTs are unstable in Mixbus 3. I don't want their plugins. Not yet at any rate.
With 3.1 coming soon with CS support I am going to use it more than I did version 2.
Over all its a good DAW that needs a bit more development but its on the right track.
