Can you re-calibrate the pitch control on Traktor 2

its a long story, but ever since accidentally chucking a pint of beer over my Omni controller, rather unsurprisingly things don't work as they once did,

having said that, most things do seem to work, except the pitch control on deck A.

whenever I touch the slider on the Omni, the pitch defaults to a much slower pitch.

it feels like if I could just re-calibrate the pitch or re-set it or something.

i don't want to have to chuck the whole lot away just because of being clumsy.

thanks - newbie on here.

clean it with some contact cleaner and see if that helps...
