It could open up new possibilities for the right musicians, I think, the way Stevie Wonder can do so much more with his chromatic harmonica. I'm a little worried about changing the ergonomics of an instrument that's already trying to destroy your hands if you play it just a little bit wrong for enough hours, but time will tell.

"instrument that's already trying to destroy your hands if you play it just a little bit wrong"

that's not the fault of the instrument, that's your fault.
