I have used Sonar in various formats over the years, and feel very happy with the new Platinum edition.
I am using dual monitors and feel it would help workflow if, while having just the console in focus, it was possible to split the bus from the track view, thereby allowing a better usage of the mixing desk. I am aware that this can be done by stretching over two screens but this practice is a little Heath Robinson.
Just to say well done to the Sonar team for this assume bit of kit!
