Hello.. sometimes i have a strange problem with my Xponent (and Traktor pro).. Some button-leds like low-kill.. or filter-on etc.. don't respond right when are pressed or not.. to example.. on software i have the low-kill ON and the led on button is OFF.. or viceversa.. or sometimes the led on button remain ON or OFF not depending from software.. I have already tried to reset the midi signal or add-in other times.. but still not work.. sorry for my bad english..
