As far as I could see the links were correct. This phone works differently enough from the old one that it concealed whatever the problem was.

Anybody got something substantial to say? The mechanisms they talk about are rather like the modal modulations I described in my modes tutorial - opening and filling gaps (“indels” in their useful terminology). It’s a kind of “ontogeny recapitulates phylogeny” situation - I was talking about compositional processes, they’re talking about historical ones.
