Hi, thanks, Access Mode had not worked unfortunately, neither had Infrastructure Mode which I usually use, although both ways connected the Genos to the Router ok, and the Genos appeared as a connection in the Chord Tracker App. But after much head scratching/trial & error, it turned out to be my 'stripped down' OnSong midi template.
I have everything turned off in this, except a couple of CC and PC permissions, but as soon as I switched 'Receive' in System/System Exclusive Message/Receive to ON in page 2, all was ok again. I was clutching at straws until I tried this
