pad sensitivity

I tried turning the sensitivity down to make my drum sound more natural, to vary the velocity, but it doesn't seem to make much difference, even with the lowest setting. Does anyone have advice on how to take advantage of this feature. Also is there a way to reset the pad sensitivity so all pads have same setting, for some reason mine are all different even before i changed any of them.

turn full level off, or try to change the velocity in the step edit page.
Besides try to experiment different levels of pad sensitivity and choose the right one for you.
