I run AX8-Edit on my Surface Pro. I find that some of the knobs do not respond well to the touch screen. Sometimes, I have to drag my finger all over the place to get a knob to respond AT ALL. Sometimes, I can input values with the keypad, sometimes I can't. And sometimes, I have to input a value using the up/down scroll, and it is VERY slow. Is this a Surface Pro-related problem, or an interface thing, or a problem with AX8-Edit?
