My Artist Mix supports Eucon, MackieControl, and HUI. The Eucon software has settings that can turn those Lan/Ethernet signals into the other formats for use in DAWs that don’t support Eucon. I use my Artist Mix in Studio One this way (S1 offers no Eucon support).
I wouldn’t be surprised if Steinberg doesn’t release any updates to Eucon at this point because they don’t want to do anything to strengthen Avid’s hand. It may have been one thing to support Eucon when it was just Euphonix developing it, but now that Avid has taken over, has Steinberg released any Eucon updates since? I hope I’m wrong on that because ultimately the end-users suffer by having more limited options and less competition, but I’m not optimistic.
