I buy a used traktor S8 controler and at the first use I noticed that the knobs and faders of side B do not work properly, after reviewing the mapping and calibrate the controler it happens that they work correctly from 0-50 and 100 but when you move the knobs and faders slow within these values (ej for an intermediate value as 25) it moves randomly the value without going up or down gradually .. for example when climbing from 0 to 50 instead of going up gradually seesaw continuously until reaching 50.

I hope it is understood, i downloaded all the programs from the official website with the license.

THANKS!!
