Somethings are best done live, and while there is a lot of things evolving in the midi world The ones mentioned are certainly the most problematic. There are wind controlers for wind instruments but i do not know of Harmonica and vocal tools. There was a program that converted Audio to mid as long as it was one track and simple. And as Mac said melodyne. But still it would be very hard to reproduce the sound afterward. What vocal synth comes close to the realism of live vocals.
