I can see why CW is very proud of this. It is a very well thought out addition to Sonar Platinum. It works too. I tested it and it did what CW said it would do. What was surprising to me was how quick it was. This region FX ability within Sonar is pretty fancy and seems to be a great addition to the program.
My view though is CW should be ecstatic about Sonar Platinum in general. It is a cut above Sonar X3 in stability and it just works well. Its features are fantastic. One can get used to this kind of luxury in a DAW that seems to work so well.
As good as X3 was Sonar 2015 is that much better.
CW should bask in the glow of a great release. A job well done.
