If I use MME drivers everything seems to be completely off tempo. Never tried it again after that. My drums necessitate the usage of VSTi to get a better and more realistic sound than if I were to be using SoundFonts.

The issue I've been having is solely with the latest two versions of PowerTracks. Everything before that worked fine, even when I was once using crappy Windows Vista.

I can't even get PowerTracks to work properly with an M-Audio Mobile Pre setup that I recently was gifted, while that works fine with Protools 9. I would be abandoning PowerTracks completely at this point if it wasn't for the fact that I have songs that are unfinished in Powertracks that I need to export since the SEQ files are not something that any other music software out there will import.
