A peculiar and very intersrting digital wind instrument oriented to theIrish wistles and bag-pipes music is the WARBL

I assess the new digital music instruments and software fromthe degrees of freedmon the allow to the player.
The warbl does not allow yet for any possible tuning of any note on any of its virtual holes=buttons, but the designer has written that he will consider it in the future.
What I like in warble is that it is based on the simple fingering system ofthe irish whsitle of 6-front +1 thump hole which is also the universal smartest fingering system of all folk direct flutes among any continent.
Unfortunatly some digital wind instrumenst are based on the fingering system of the saxophone, or recorder , or clarinet, or Bohm flute which are not the smartest and most ergonomic possible for a wind instrument. But not the warbl. The Warbl is based on the smartest posssible fingering system the irish whistle. Of course it supports other fingering systemsl ike that of recorder and native american flutes etc as well.
An interesting feature of the warbl is that the bending of the notes and partial holing is not supported by any sliding special button as in other digital wind instruments but by optical sensor by the distance of the finger from the hole.
The current design state of the warbl (2020) supports only 2 octaves with the tumb hole and 3 by utilizingthe right thumb and an additional button. But the designer has written that it will give it 3 octaves inthe future only with the left hand thumo button.
