Hi Dave,
The Network port on Qu mixers is only for control data. It doesn’t stream any audio.
The main reason why the DAW Control driver allows TCP/IP connection is to work with GLD (which doesn’t have a USB B port).
Does the fact that I can send midi data over enternet mean the QU can or in the future be used as a surface to an IDR rack?
No I’m afraid. That would require a significant amount of software to be written to allow the Qu to connect to the iDR host via TCP/IP, and the messages of the MIDI strips to be user defined. Also although the MIDI Protocol might look similar in places, comprehensive iDR MixRack control is only possible through our proprietary AHNet protocol.
