The most important ímprovement that both Technics and Yamaha must do is a manual bass part, for easy choose of bass voice, and a manual bass on/off button for easy use of either left hand bass or bass pedals.
It would be ok if the choose of manual bass would be for left hand bass, with right hand recognition, or for bass pedals, with left hand recognition, inside the menus.

Listen Yamaha. You MUST have this on your next board !!!
