Hi all,
The messaging protocol used by the console and apps is classed as an IP asset and for that reason, not public.
It also changes, which is one of the reasons you must always use matching major revision versions of firmware and app, so you might end up re-programming for every release…
The public remote control protocol is MIDI, but as Max has pointed out, does not include channel selection data.
This is because MIDI control of the console is to and from the core (rather than to/from the surface or any app) and different channels can be selected on the console and any connected instances of MixPad.
i.e. the actual mixer is not what you see, it’s the XCVI core and the control surface, apps and MIDI are all just different ways of talking to it.
Not to say this would be impossible though and there is already a feature suggestion thread for it here – https://community.allen-heath.com/forums/topic/select-button-triggers-midi-note – so do comment there if it’s something you need (along with a brief description of the use case please!).
Thanks,
Keith.
