The 64 bit version in my opinion is not stable with any of the VSTi plugins I've tried, I can get Sampletank to work when I only load a single instrument such as "Piano", but as soon as I added a second instrument such as "bass", it became unresponsive when I try to play the song, all I hear is static, I can't even kill it in task manager I have to reboot the system, Kontakt seems to be more forgiving because I can kill BIAB in task manager when using it, but the results are similar. Right now I find the 64 bit version only usable with Realtracks and I've given up trying the VST too, it's not usable either. I just don't have the time to spend working with something that is this unstable.
