I have an AP APx audio analyzer, which is capable of generating and testing 16 channels via ASIO and a connected MADI interface. Ideally, I would like to generate a 64 channel MADI link and route it via a MADIface to my DUT and back to analyze it. Is there any special gear for testing MADI, so far I haven't found anything but the APx solution.

Thank you for your help.
