Pro Audio Support

Q:
When I change a plug-in parameter with my control surface (Pro Control, Control|24, HUI, Motor Mix, etc.), the save light doesn't come on and save is grayed out in the file menu. Making the same change with the mouse causes Save to become available.
 
A:
At the time of this writing, this is a known issue in all versions of Pro Tools (up to version 5.3).
