In my opinion one of the best digital wind instrument as midi controller is the SYLPHYO

I assess the new digital music instruments and software fromthe degrees of freedmon the allow to the player.
Some of its advamtages over other digtal wind midi controllers is that it alloes for many different fingering systems which includes of course the simplest and universal one of irsh whistles and folk direct flutes like quenas, Xiao, shakhuhachi etc
What sylphyo unfortunately does not allow (but neither any single tube digital wind midi controlleras far as I know) is to set any possible note to any ofthe virtual "holes" or finger buttons.
It does allow though for plenty many different fingering systems of practiacally any known wind isntrumenst at any key.
Only the Swedish digital harmonica DM48 allwos it but it is not a single tube wind.
One of the best features of this SYLPHYO that I enjoy a lot is that it has a triple registry-thump key which is actually 5-fold and a allows forthe wind instrument taht you paly to have not 2 not 3 but 5 octaves while playing real tume.
Furthermore I enjoy a lot the easy design of sharps and flats which is simply by a single (correspondigly ) button for all notes (like a pedal in orchestral harps) controlled by the little fingers.
Furthermore the slider that it has controlled by the right hand thump makes miracles in effects on the sounds.
Because the SYLPHYO is a midi controller triggering notes by the breath pressure and finger buttons, it is still an excellent tool for excercising the breath and having high emotional involvment while playing because of the breath.
