+1 here for a 32-bit version, because I'm still using a Yamaha SW1000XG; works great, but only has 32 bit drivers.
 
If anybody knows of an accurate softsynth equivalent, please speak up!

Anyone want to buy a t-shirt?

As a long-time SONAR x32 user, so far I've been pleasantly surprised. Cakewalk X64 is opening up all my projects and playing them flawlessly. Yes, I did have to go back to my download folder and re-install some of the bundles, this time selecting [x] 64 as well as [x] 32, but after that... no problems.
 
I can see that CWx64 is opening up 32-bit VSTs where necessary, but... it's all working!
 
I may have been turned into a 64-bit convert. Finally.
