I got the Atom controller and all is working except the pads do not control Impact XT. The knobs do what they should but the pads do nothing, won't trigger. As a MIDI controller in BPM it worked but not Impact XT. Any ideas? What am I missing here. Should just be plug and play correct.. The weird thing though is that when I select the pad with my mouse and change the note value at the top right, the pads will select the note but not play the sound in the pad..
