so when ever i press down on pads 1 and 3 simultaneuosly, the sound from pad 4 will activate and cancel both 1 and 3, so if 4 is a crash it will cancel out 1(kik) and 3(hat), this also applies to pad 2(snare)...just whenever i press 2 pads at the same time not being pad 4, the sound from 4 cancels everything, i hope i explained this right
