xxxsoundxxx, Of course you are right, but I think the reason is that we hear so much about large facilities using ProTools that some users like to affirm that Sonar productions are getting air time and sales.
I agree that no one would ever be able to listen to a professional recording and say, "Oh that is ProTools," or "That was made with Sonar," or "Obviously a Cubase production." Something I record sounds totally different than almost anything else, but that is not Sonar's fault (or credit).
