When fader set to sharpest curve/scratch mode, and fader all way to right hand side, left deck can be heard. cues stop Does not appear to do this when X fader contour is set to anything else.
So the only setting for scratching, is not allowing scratching.
This did working initially, but since buying in Nov 2016, more any more problems have been experienced, cues and headphone pots stop working, Cue buttons dont start tracks and have to push the platter to play.
Restart usually fixes but not ideal for live gigs.
