I am not annoyed I was trying to HELP you because you said Liquid MIX and other things in addition to your query about the Fovusrite/Roland lashup.
NO I dont use both, but you should know that even though the Saffire has ADAT I/Os that the MIX control only routes the SAFFIRES I/Os among themselvesit is a patchbay/mixer,
SO even if connect 8 mics into the roland, send them to the Focusrite via ADAT,\
these eight mic signals are routed internally in the Saffire Mix Control as 8 sources to the hardware outputs, 10 analog(two are headphone), one adat and one spdif.
Since you have a patch panel that accepts analog signals the EIGHT SAFFIRE audo outs could go to the patch bay, and in addition the eight Roland audio outs , (and you can do the same with the inputs for HI-Z stuff to your patchbay.
Since you said VARIOUS MIXERS, you might have more flexibility sending the outputs of the two hardware audio interfaces to these mixers through your patch bay and not even use the MIX CONTROL
Basically the Focusrite Mix Control is a software mixer patch bay but even though there are so many scenes and listings, there are only the fixed Input Output configurations.
