TORAIZ SP-16 : Add all synthesis parameters of the AS-1

I would like to buy the AS-1 so I can control it from the  SP-16 but when I checked the available parameters on the SP-16... there is not enough there. Please add all synthesis parameters in the list!
The AS-1 has almost all its synthesis parameters controllable by MIDI CC so there should be no problem implementing this. Why  limit this?
