I don't need updates. Sonar in a way has way too many features for my needs.
What I would like is if someone took Sonar and obliterated all the bugs. It has so many little bugs, most are not show stoppers, but software should never crash, and Sonar still does. And this is one reason most others might not want to touch it with a 10 GB pole.
Myself I'm really not expecting Sonar to carry on, they just lost half their user base and each day they are probably loosing more. It was loosing money, it's full of bugs because of bad decisions made years ago.
But it's still my first choice as a DAW even with it's little bugs. If those were removed it would be perfect, but there's a 1/1000 chance of that happening.
