Dorico putting multiple instruments/players into one channel in the mixer

When using Kontakt, you need to set the Kontakt outs up, as I explained in this thread.
[Edit]I discovered in the meantime that the possibility of showing the outputs window in Kontakt 7 had been made impossible if you chose to show Kontakt 7 as a minimum sized window (which is something absolutely wrong from a GUI point of view, I think — it was already complicated, now it’s utterly absurd!). I will edit my post to troubleshoot that situation!
