Hi everyone,
This is an old thread, so I'm posting an update just so there's no confusion.
With the release of VENUE 2.9 software it is now possible to use an HDx and MADI card at the same time in a Mix Rack, in a mirrored output configuration (i.e., sending the same signals from Mix Rack to HDx or MADI). More details on the
software page.
