I don't know if this would be of any use to you, but I have a physical
controller that sends messages about its full circular direction. I've
made to work with midi like this;

1) The circle is a square mapped to two controlvalues Left/Right
Front/Back. You start at the center of Front, walk all the way to the
Right then all the way to the Back then to the Left and back to Front
again. Pretty much what a joystick would do in its extreme positions and
works well with existing gear. Recommended!

2) Still two controllers, one sends the initial angle where you
touchdown, the other sends delta values as you move around. 

A bit harder to fit in with existing gear, unless you want to play your
faders like a violin :)
