Much appreciated Vintage. I see now how difficult the question is to answer without the cross/channel distinction. And having now read that “all non assigned channels stay active” in a digital copy of the M6 user manual, I see how illogical it would be for a channel to simply go dead when unassigned. Perhaps the fear of a new toy with the same limitations as my current two channel clouded my judgement 🙂 Thabks again for the info.
