How do you play sharps and flats that you dont have on your concertina?

I don’t know anybody who has tried (much less seen) a Wakker H2, with its 65 keys, one bisonoric (eb3/f3). But there it is.

As I understand it, this bisonoric button is a result of classic handstrap reach limitations. I faintly recall it mentioned by Wim himself. The original H-2 had 64 buttons and ended on E. This Eb/F button is not only bisonoric, but also out of pattern, as those notes are played with the thumb. As such, this $9k instrument not only cannot be primed or closed without sounding a note, you also cannot increase the rate at which the bellows closes/opens to prepate it for the long phrase mid-tune - a feature of an air button (lever in my case) that I use quite often. As I said earlier on numerous occasions, I’m not exactly a fan of Wim’s design choices.

Bizarre!  If true then I would remove the Eb3/F3 reeds and have an air button.

I can’t remember when or where I read the „origin story” of this design choice, but it is there in the button chart for H-2 on Wakker site.
