I have pro tools 10 on a PC with Windows 7 Ultimate. It works fine with my Presonus 16.4.2. Not so good with a Mackie 1640i or 1220i. I have gone to the Mackie site and loaded current drivers. The Mackie works fine with Sonar 8.5 and X. If the Mackie is plugged into the firewire port and I click Pro tools it starts to load and then I get the BSOD. It seems to hit the Loud drivers, at least it references them right before the memory dump and reboot. Anyone have a work around? Does the Mackie Hardware work with Pro Tools 10/Windows 7?
