I bought the MP3 app for Sonar so I never again have to worry about having to export to wave then convert to mp3.
Direct export of MP3 now from Sonar X2, woo hoo!
This works out great for me because I am now testing out my mixes on a MP3 player to take to the car, home stereo, and boom box first, without the need to burn to CD. This seems to be working out for me.
