The Pro Tools automation problem that arose in V2.1.0 of PhoenixVerb (stereo) and R2 (stereo) is now patched in a Beta that is available for both OSX and Windows. The new version is 2.1.1 Beta 2. The previous build covered only OSX. The Mac beta has been updated as well, but there are no significant changes from Beta 1. This is available to any license-holder.
If you'd like to work with the new Beta, please visit the Stereo Beta Download Page. Thank you for you patience. It is hoped that the update for Windows surround will soon be available.
