Bisonoric Meets Unisonoric

[Takayuki YAGI]

In the recent ebay listings, these odd ones cought my eyes.

 

This German one seems to have LHS of Anglo(bisonoric) and RHS of piano-duet(unisonoric).

And this rare Jones has 20-button diatonic(bisonoric) core with chromatic buttons(unisonoric).

 

I am not sure if these systems were useful in some situation, but anyway, interesting.

I've always been surprised that so-called "mixed systems" have not caught on more, particularly with 2-row bisonoric button accordions, which in all-bisonoric form have infuriatingly, moronically, uselessly, limited left-hand bass capabilities. The right-hand treble side is fully chromatic on "semitone" bisonoric accordions. But the left side is just stupid. So easy to put a 48-bass or 60-bass stradella there so you can bass the thing in all keys.

Hello, I bought two years ago a concertina that it is almost the same that the concertina showed in the ebay listing. And yes, the left hand is bisonoric.

I can send the layout of the left hand if you want. It is really big.

The concertina that I ordered isn't playable, it would need a repair service and I didn't send it by now for the service.
