PSPaudioware has added support for the new Avid AAX 64-bit plug-in format to all their delay plug-ins: PSP 42, PSP 85, PSP 608 MD and PSP Echo. This is a free upgrade for current users.
Nothing else changes (even version number of the product) so if you are not a ProTools 11 user on Windows do nothing.
