Notice how in your VEP that they all output to “1 Master” ? So VEP is sending everything on just one audio channel back to Dorico.
Versus on my VEP, notice how they are all different: the first outputs stereo to “out1/out2”, the second one to “out3/out4”, the next to “out5/out6”, and so on? So on my VEP I am sending many channels of audio back to Doico, and yes they show up separately on the correct Dorico faders for me. Apologies that I didn’t screenshot levels during playback.
First thing I do in VEP is delete the master channel, unless I really do want just one audio output for some reason. That help?
