I came across two Pro Tools 11 reviews and thought, the internet needs to read this! Very useful information on the Pro Tools 11 changes, pros and cons. You can read the Pro Tools 11 Review here and you can also check out the Pro Tools 11 Review For Post Users here! I think a big concern for a lot of Pro tools 10 users is losing plug-in compatibility with the shift to AAX. I personally own many plug-ins that have not yet released an update to support AAX. Toontracks Superior Drummer have released an update and that makes me very happy. You can always refer to Avid's AAX plug-in compatibility page to see what plug-ins support AAX.
