Joh the Tyros 3 will send midi to host over USB. So you should be able to control say the B-5 drawbars from the 9 faders on the Tyros, the Leslie fast, stop, slow from the modulation wheel and map whatever else you would like to control.

Whatever you get you will need to get an understanding of midi So why not start with the Tyros you all ready own?
