Thank you all very much. With the information so far I have decided to call Cakewalk today to confirm that TTS-1 works with Vista and Windows 64-bit OS's and that it recognizes all GM and GM2 bank changes. I am concerned that the sound from TTS-1 is not highly regarded on the Sonar Forum, as indicated in one of your responses, but at least I can use it until the ForteDXi update implementing full bank recognition comes out.

I and also leaning toward installing the 64-bit W7 upgrade when I receive it.

Thanks again for all the helpful and interesting information. I wish I had started posting on the forums eight or ten years ago when I started using BIAB. Regards, Scott
