Question

Thanks for such a thorough answer, one addendum. When you switch the mixer to 96K does the 32.4.2ai take the current sub group eq and fat channel settings & apply them to the outputs, or does it revert everything back to flat line eq?

Answer 1

The DSP is turned off, but settings in the application always report the same.  This is visible in the UC Surface Software when open, as you see the micro view "greyed out."  The moment you turn it on, it will come right back up with the prior settings you have, or whatever you recalled in the scene prior to the switch.
