sort of pan flute, but with reeds ... ?

Ah, so, there is only one air entry, plus something that must route it ?

It may be not what you want: think of medium pressure valve routers for
_dental industry_ (google: valve routing).
You may get better ideas on a mechanical musical instrument list, maybe
by browsing the mail archive of http://www.mmdigest.com/ (though there
must be other mmi lists)
