Thanks, yes, I had a nice lunch.
Now to NP: It doesn’t matter if M1 compatible or not, that is the way NP works, it has it’s own mixer and provides only a stereo out per plug-in instance. In this case, those 2 stereo outs go to the first 2 channels of the Dorico mixer. The Dorico mixer picks as channel name the name of the first slot of the NP instance. This is as far audio processing goes. All other faders to the right are actually MIDI faders. So they send MIDI data to NP and by that you can still level out the instruments within one NP instance even from Dorico, So it is a kind of remote control then.
Did this explanation make it more clear?
