problem with my s4

I had the same problem. thank god there are two decks per jog wheel. made life a bitch but lets you keep going.
…anyways quick fix I found halfway through the set was to play the track (even if the song doesn’t “play”) then give the jog wheel a firm nudge in the fast-forward direction and it should then be able to que up/play/whatever as usual. I think the issue is that the hardware is too sensitive and believes you’re holding down the jog wheel, which is why even while it’s in play, it’s paused. nudging it is tells the jog wheel what’s up. That’s why (I assume) calibrating the wheel fixes it.
