I have published the problem here Engine prime & MCX 8000 Problems resolved and new ones but there is still no answer, I made an exhaustive analysis of the problem and it is with specific clues, they are exported perfectly with their cue points (I could verify it by loading them directly to the usb after exporting) but the mcx 800 does not show them, the tracks with which this happens are always the same send some to denon to see what the problem may be but do not respond
