I don't think so, I'm already looking into that, it does work with the other bit bridge-like program that sonar supports, I forget the name right now. Not sure if they've fixed it yet, but last I heard sd didn't work properly with the cakewalk bit bridge; I think I read somewhere that sonar78.5.1 fixed this issue though. If you don't have 8.5 you can perhaps use the other bit bridge-like program, maybe somebody else can chime in with the correct name for the program... Or maybe toontrack will release a x64 bit version. Hmm actually, not sure if version 2.2 makes this leap already...

Do anyone of you know if superior drummer will work in a 64 bit environment? Let's say I use a 64 operating system with sonar 32 bit. Will sd work?
