    I get what you are going for but the Slave part of MOSI and MISO does not in fact refer to using a device in slave mode, rather it refers to where the wire would be hooked to for a Slave device if...

    There’s no reason it couldn’t, it’s just a matter of porting it over since I haven’t had time to make an easy wrapper library yet.

    From my understanding this Ethernet audio library only works from Teensy to Teensy, would it be too far out of the question to ask about supporting a standard like Dante?

    That's fair, looks like only profiles are supported in MacOS 10.15.4 Beta right now so it'll probably do a while before it's completely done for an official release.
