X3 Producer continues the Sonar tradition of innovation, new features, new plug-ins and bang for the buck, with Melodyne Essential and Addictive Drums also in the bundle. My favorite new features - track & bus colors, comping workflow, and Quadcurve EQ Zoom with Analyzer. I'm happy that several updates have already been released to improve usability. It's a solid product that is already more stable for me than any versions since Sonar 8. I'm with-holding 1/2 star because it seems there are still a few bugs and glitches, some new and some which have been around for awhile ... none of these are showstoppers for me though.
