It strikes me that it is not so easy to produce very short notes - like thirty seconds and sixty fourths - on the wood winds (it is merely my guess, I don't know for sure). Perhaps, it has to do with the fact that wind musicians can't quickly start and stop exhaling. On the other hand, I've noticed that brass winds, like trumpets and trombones, are quite good at producing short notes (so maybe it doesn't have to do much with exhaling but with something else that brass have, but woods don't). Perhaps, the easiest instrument to produce a short and relatively loud note is a xylophone. Is my guess correct?
Scope of the question: In my question I am inquiring only about natural instruments, that is, the saxophone and those instruments that were invented before electricity was discovered. Also, please, exclude the piano from the scope.
EDIT: Please, exclude any unpitched instruments, too.
