Included in the tones are 50 Drawbar Organ tones that can be adjusted using nine sliders that function as drawbars corresponding to certain ranges of overtones. Users can also change the speed of the rotary speaker effect and add percussion at the press of a button—making the enjoyment of performing come more and more alive."
