I just came across this old topic, as I'm also interested in the MIDI Wicki-Hayden concept. I've never actually got my hands on a duet concertina, but I was thinking of basing the key layout on the Beaumont. I just wanted to check whether that was a sensible idea, or if there were any alterations that duet players would make to that as a starting point. (I'm aware of the debate over straight/slanted layouts, though I don't know if there's a clear preference one way or the other.)
