Korg removed the sliders on the Pa800 to reduce production costs. In OS 1.5 we will get virtual sliders instead, i.e. you will be able to adjust the drawbars directly on the touch screen. It will never be as good as real physical sliders, but at least it is better than the current situation where you have to use a combination of the touch screen and the scroll wheel to adjust the drawbars.

Kind regards,
Tommy
