Tried every configuration available:

Carbon - master, daisy chain WC to Midas 1 and 2
Carbon - master, split word clock to Midas 1 and 2
Midas #1, master, daisy chain to Midas #2, then to Carbon as WC slave.
Adat as clock source from Midas 1
Adat as clock source from Midas 2
WC terminated and non-terminated.

In all instances, interfaces and preamps show green (good) clock.

This is a new system, new Mac mini (running Catalina 15.10.7)
So far, no success with Sweetwater or Avid. back on the phone tomorrow am.
