Many thanks for your attention.
My main concern at the moment is that the channels showing up in the Dorico mixer don’t seem to bear much relation to those set in the outputs panel in Kontact - see the pics earlier in the thread. I had hoped that the instrument labels would correspond with the actual channels playing in each column of the mixer, and that the output labels would match the Kontact ones - eg st1, st2 etc. Also some instruments seem to appear twice.
I’m not sure about the dynamics control at the moment. I’d rather stick to sorting one problem at a time, if possible. It’s taken quite a long time and much effort top actually get to the point where I can use my old GPO v1 instruments in Dorico at all!
Regarding your point on the Endpoint dialog, it shows all 8 channels, although only the Kontact cello is being used - see the pic earlier in the thread. The other instruments are HALion SE. Sounds like that’s wrong then? But how should I correct that?
