Earlier I was reading a description that @Bruno posted in another forum…
“Horizontally, in a row, you have semi-tones. Vertically, from one row to the one just under or above, you jump of a third, and you have to go left or right to get a minor or a major third. If you jump two rows, then you can find a key that is vertically aligned with your start key, and you have a perfect fifth. Then if you jump to the next row, you will have a 7th, and you would have to choose the major or the minor one. It also means that on the same row of the perfect fifth, you have the augmented and the diminished fifth.”
…but I can’t really imagine what that’s like.I might have a go at copying it on my Axis. @Clarinette pointed out that there’s a useful online hex layout player here…

(The Terpstra was an early ancestor of the Lumatone.)
I’ve tried a couple of different concertinas; an Anglo, and I’m currently messing around with a 48-button English, but I’ve always been intrigued by the Wicki/Hayden layout and I’d like to get hold of a Duet sometime. The tunes posted by @Didie, who commissioned the first “Striso duet”, have done nothing to put me off…
Great playing. (Lovely instrument too, a Beaumont from The Button Box.)
Back on topic though, the scales on the Exquis are customisable so you can set it up however you like.
The default layout on their previous instrument, the Dualo, was split across the left and right hands as you say, but I never got the hang of that. The Dualo had three or four preset layouts, and I ended up using one called “Universal” (which is the one @Clarinette also uses).
