Hey guys, i have an issue with the shift function and would like to know if it's only in mine djc-4 or yours too. When i press shift and turn the bass knob, it adjusts the filter, as it should. But when i take my hand of the shift button and turn the bass knob to adjust the bass, it doesn't do anything until i put the knob in zero (0) and do it again. Only then it can adjust the bass. I don't know if you understand me, because my english is not so good. The same applies on the mid knob (which adjusts key with shift button pressed) I also tried Trigger mode on shift button from the instruction manual, but nothing changed. Also, it does it on Virtual DJ LE, Traktor Pro and other programs.
