two sliders at once?

is it possible to throw two different effects from your sliders onto one sample? i only hear one working...

yes it is possible. It should work if you assign slider 1 and 2 to the same pad.

nope, you don't assign sliders to pads, you assign pads to sliders and only one sample per slider. you could put the same sample on two pads and then assign a seperate effect for each slider.
