I have played around with it for about an hour - so far no issues at all. 
 
since moving over to Mac I have been unhappily devoid of most things Cakewalk.... BUT getting DimPro and Rapture back, albeit in a new and exciting package, is really inspirational! I have already created, modified and stored a heap of new sounds that I intend to use in one thing or another. And it sounds as good as ever. Very happy here, hope the rest of you are too!
 

I can't believe how easy it is to import your own samples and really mess things up with this instrument!!

Lucky you - despite using Cakewalk Command center mine keeps on saying it's a demo version.
 
Support said they will have to get back to me tomorrow. Sigh...

We're feverishly working on our end and are fully aware of this issue. Apologies!

Im a mac user who has old projects (2003-2006) that used Rapture and Dimension Pro. Rapture Pro's compatibility with the lastest OS X has allow me to relive these projects within a single interface.  Besides some annoying bugs...I am hopeful for a great experience.
