an other problemmmm......!!!!!!

Maybe its really simple, or my mpc is fu**ed up!!! I'll keep it simple, when i make a beat, if I press the ''note repeat'' button,
pad 6 and pad 11 are allready ''assigned to it'' like automaticly.... As soon as I press note repeat button, I hear the 2 sounds that are on those 2 pads play at the speed that I choose no mattter what I do.. ssoo then If I want to, for example, take the sound on my pad 2 and make a 1/16 note repeat onto my beat, i cant cause the two other sounds starts playing automaticly like if a ghost what pressing them both (no mather what program)!!!!!!... Am I clear ?? or ? I hope my mpc's not **** up!!!!!

thanks

yeh i get that on my XL sometimes, it normal goes away just like it appeared, randomly!
