The Yamaha "Wind Jamm'r" EW20 Electronic Wind Instrument was released in 1989 by Yamaha's Band and Orchestra division and that is probably why no one really knew about it.  It is midi capable and both the tone generator and controller were sold together as a package.  

This one comes with the original instruction booklet and a small Yamaha speaker as well so the entire package makes it easy for you to play it without any large PA system.

Good condition and the owner tells me that it all works.
