This sounds like a problem with 32 bit plugins on a 64 bit Win 7 machine. Nothing to do with the version of RB. 32 bit Programs run fine on Win 7 64 but plugins don't. They have to be 64 bit. There could be other 64 bit compatibility issues but check those plugs first.

Bob, this has not been true for me. I have a raft of 32 bit plugins that I use on Win64. My host, Tracktion, is 32 bit, as far as I know, and all of the plugins that I use are 32 bit.

I run Tracktion as administrator. I've had zero compatibility issues with my 32 bit plugins.

One other thing could be that the op is running into multi-thread incompatibility. While my Win764 bit box is quad core, I can only run Tracktion on 2 processors (there is an option in Tracktion to instruct how many cores it can use). If I try more than that - screech, scratch and general audio mayhem. Finally, there are some simple tweaks for Win7 which I would try first, prioritization of audio, etc. Presonus seems to have the authoritative resource on this now, where it used to be that Tascam document.
