Biab is 64 bit compatible but that doesn't mean a VSTi is. Two different things. A VSTi is a software instrument that must have a host. Biab is the host in this case. I don't have a 64 bit VSTi to test but I'm pretty sure John is right, Biab is a 32 bit program and most likely can't host a 64 bit VSTi.

This is yet another layer of confusion for users because most 32 bit programs will run fine on Win 7 64 bit. An example is my Sampletank. It's 32 bit and they have not yet released a 64 bit version but it works fine as a VSTi on a 64 bit system. As I've tried to explain to our friend Ron and given up on, we have to read this stuff carefully, keep ourselves up to date and turn ourselves into computer nerds in self defense otherwise none of us will have a clue. This stuff is constantly changing and evolving.

I'm right in the middle of this right now because I just bought a custom AMD Phenom 6 core with 4 gigs ram and Win 7 64 bit last weekend and I'm having just a wonderful time porting everything over (not). I've already run into some glitches that I had to chase down but it's all good so far. An example is one of my USB external HD's shows up in "my computer" but no data. I plugged it back into my XP machine and it's there. I was pulling my hair out until I found an online forum explaining you have to go into properties for the HD and switch it from the default "easy eject" which is a new Win 7 thing to whatever the other eject option is called (can't remember it now). I did that and voila' there's the data. Sigh. How's that for intuitive? Whaddya mean you can't simply plug in an external HD and read your data? What, you want easy??

I know there's more things like that to come.
