@Peter-Ostry ha peter maybe i'm not clear. the sylphio can translate flutists playtechnique (vibrato) to expressive sound / pitch message. listen to:
https://soundcloud.com/tilo-baum/19-08-23-vcv-respiro-2
there I used the possibility in "respiro" to translate breath control to pitch variation (+/- even 0.4 steps at 0 respectively 127)
but respiro reacts so slow on the other hand the preset sounds are so much faster.
but I really regret that there is preset vibrato in a lot of the sounds and that the air vibrato can't effect any pitch...
and off cours I do not wanna recreate a flute..
I wanna amplify the expression possibility of sylphio. and I'm shur I could If I had contact with devellopers
