Reply to Please help... Traktor with vestax vci 400.

Hi all.

I'm new to vestax combined with traktor so I do appologise if this is something simple.
Iv loaded my mapping for vci 400 into traktor and everything is fine apart from I can't scratch. The mapping set from a friend are on his traktor and he CAN scratch?? Iv checked in the mapping and i can see the scratch on function has been mapped.Iv tried altering the sensitivity and.. Nothing.. The jog wheels do alter the tempo, change colour when I press, and also stope the track when pressed. I hope it's something simple.

Thanks for your time all

Luke
