What I'm batting at, I suppose, is this.
The difference between Platiinum and Professional, more or less,
is the "add-on" stuff. Look down the comparison chart here.
http://www.cakewalk.com/Products/SONAR/Versions#start Now, in terms of buying into the Platinum tier in the first place, well, like a lot of us I'm sure, I'm well-covered on that; been paying for the top end version for years.
What's niggling at me is this: looks like there'll continue to be a Platinum monthly / annual fee that's higher than the Professional monthly / annual fee. But doesn't look like that higher fee will get you anything extra.
