I was hoping someone might be able to shed some light on this issue please.

I have a 2 x 1210 and djm-250 setup and am having issues with the x-fader settings.

When its on the smooth curve the fader works as it should, fader to the left and only deck 1 plays, fader to the right and only deck 2 plays.

Now the issue is when I flick the switch to the sharp curve. Fader to the right only deck 2 plays (as it should ) but when I slide fader to the left both decks are playing

Anyone come across this before, it cant be the x-fader can it as it works normally on the smooth curve
