Fine, no more Sonar development.
Did your copy break?.. nope.
I see nothing compelling about any other DAW out there..ie there is no DAW that is better in every respect vs Sonar, for if there was, I would have it already, so I am at kinda a loss as to why folk are running off so quick.. after all, had this been Sonar X5, you would have had no new features for another year..
Sonar is relatively bug free, feature rich, and highly stable.. another year or two or even more and mebbe, but until there is a DAW that is better across the board, unless MS breaks Sonar with an update, why would i switch?..
