ok after thinking about it a bit more, we where showing a bro the decks and pulled the usb to show him the safety loop and after that the deck started to occasionally glitch and pop off beat, however that issue got progressively worse, and i'm not sure if it was only the one or both to be honest. however there's another issue where if u drop it into an auto loop then adjust the length of the auto loop it adjusts the pitch(tempo) of the track too which obviously makes the mix go off.
