I think Cakewalk made a valiant attempt to go this route. When we talk about priority customer base, potentially new customers are also priority. Expanding the market share is important to success. That's probably why CW offered us existing users a Lifetime of updates--so we may not feel as
owed something at all times, and not in a disrespectful way. Nobody complained about it, so it was a win for us users.
When we consider Mac users, we all know PT has the market cornered in DAW's, and a vast majority of their customers use Mac's (PT is
not made for Windows, I'm here to say; not a friendly relationship at all). But consider that nearly every major studio and many of the music creators love macs, that was a great thing to consider, especially considering most, if not all other DAW's run on a mac.
I applaud the openness of CW to the reality of this idea and the retraction of the effort, a welcome honesty of the company. That speaks volumes of their integrity. Will we see a version of Sonar on a mac again? Perhaps. But knowing the current alpha was a mere virtualization of a Windows-based software to be made accessible on a Mac might have really just frustrated these Mac users in lack of true performance. The third-party involved who believes this is not something of concern, should be ashamed if they weren't up-front about the performance hit. After all, for software under such huge demands you don't just port code. It needs to be native to be fully appreciated.
