I found this YouTube Video with three cats playing controllers (MIDI) that have wind, and keyed interfaces. Kind of cool. The two instruments traditionally most poorly represented by MIDI are brass and guitars; brass because there's a certain technique of expression via embouchure, and guitars because they have tactile expression. The wind mouthpiece seems more like a woodwind, which means you can control attack and velocity, but not yet pitch, like a trumpet. The keyed interface is limited in the same way as electric guitars, meaning attack and velocity are limited, compared to the tonal characteristics of a classical instrument, which are much more subtle. Still, this is an interesting display of controllers. The instruments pictured allow more intuitive playing for certain types of musicians.
