Unfortunately the template has not been updated. I'm stuck on Sonar 8.53 and I also do a fair amount of work using Reaper these days. X2's reverbs and compressors are better that what was included in Sonar, so it shouldn't be too terribly difficult to get equivalent or even better sounds using X2. I wonder if some of the crazy routings import correctly into X2.
I just don't care for the X interface and a new set of bugs to go with it. I'd be very content if they just fixed the issues in 8.53, but I guess no one will ever make everyone happy.
Glad that you got some use out of it.
