Alright, I'm back.
So this is what I ended up with:
-N12 on ST Mix.
-VST channels all out to 9/10 ... or of course split your channels up, however this is not flexible for multiple projects (Input select DAW btw)
-9/10 routed to ST Buss.
-DAW to ST is off.
-RCA or jack from ST out to 11/12 in (Input select A.In)
-Cubase audio channel with 11/12 as input.
-Monitor enable 11/12 channel and set output to N12 Monitor.
Done.
Mix completely ITB with all channels passing thru 11/12 N12 converters, add some gain for color if desired, route the post gain into Cubase 11/12 audio channel with any desired effects (UAD). Toggle DAW and ST on C-R on N12 to hear pre-post 2 buss FX!
