Just looking through the midi messages used by the Mackie and other controlers. It appears to me that it is designed to be used on it's own physical midi channel as it uses (up to) all the logical midi channels (1 to 16) and so could not work running through a midi kb for example.

MIDI Machine Control is even more demanding, although it is all sysex, and MIDI Timecode has always been recommended to be delivered on its own cable (if using serial MIDI at least).
