One thing that would be useful to have is the option to have the same stereo/mono configuration option on groups and auxes as is available on matrices. Meaning if you go from stereo to mono, you get 2 mono channels.
Your group/aux configuration would still work as before (You do the split on 12 stereo channels), but when you make the stereo group or aux mono, you get 2 mono channels.
From a workflow perspective: when you make aux 1 mono (which would be assigned to your mix 1 button on the console), pressing once would give you access to the first mono bus, a second time to the second mono bus and the third back to LR.
This would be super useful and would make the SQ an absolute beast.
The issue I’m facing now is that regularly I need to compromise on the usage of busses vs auxes (monitors). If this would be technically possible, that would be super awesome.
