Regular VCI 400, monitor cue problem

My monitor cue listen in the head phones doesn't work anymore

i have checked my settings in the "output routing"...monitor left / right in the output monitor....master left/right in the output master.

and my headphones act like master out.


i cant monitor and cue in the next song!!!

i don't know what is happening, it worked before

help please.

solve! mod can delete,

somehow, the mapping for "monitor mix adjust" was deleted, so the in the GUI it was stuck all the way to master.

had to remap the function back to the knob
