when I touch the jog wheel to stop the track and hold that point, the cue point keeps sliding back. This is happening in JOG and TT mode. Also, the platter has randomly been throwing itself forward and back in both modes, tt mode the platter whips forwards and back, and jog mode the song whips forwards and back, along with the indicator light that goes around the jog wheel. Is this product a dud or is it up to professional standards? I’m running the latest version of traktor.
