Is there a way to Direct Monitor using the new Mac pro?
Yes, but only with Steinberg-manufactured audio devices, or using the the software for your device, such as TC Near Control Panel or MOTU CueMix.
I am using apogee symphony 24 in 24 outs and the aes card
also rosetta for xtra aes
so far the set up is busting my chops
especially rosetta with xsymphony card
