“I’ve noticed in Pro Tools 6 DAE is no longer used. If DAE no longer exists as an application within Pro Tools, what does this mean for third party support with applications such as Emagic Logic Audio?”
DAE actually still exists, however it has just changed from a discrete application to a shared library. This file still lives in the DAE folder, and its functionality has not changed significantly. The only thing that has changed is the way Pro Tools and any third party applications link up to it at launch. These changes, while significant behind the scenes, don’t change the way you use the software much.
