I do not own the SD-2 but I did look up the midi implementation chart for it, it’s in your manual, and saw that the SD-2 does recognize CC11, expression and pitch bend. If you set your EWI4000S breath control for CC11 instead of CC2 you should be able to control volume with it. Set you bite control to pitch bend and you will have your vibrato.

I hope this helps.

It was the best game of Hungry Hippos I've ever seen!
