I can imagine that...it is huge challenge but maybe something to consider in future ...like modular approach...different modules...brass, pipes, flutes, woodwinds, modern synth...I'm sure there are a lot of people with slight different preferences about wind instruments.
Anyway...there is nothing even close to Respiro on the market with such quality and playability..
I have already tried Respiro on iPad...sounds great so far.
this is indeed very difficult to approach, what can be done with acoustic instruments in the digital realm. Sample-based virtual instruments have their limitation by velocity after key press. Advanced sample-based instruments can change expression even after note-on. Physical Modeling is another approach.
