Hello there .. i'd like to discuss a thing .. My Tempo fader of the deck A , Jumping slowly up and own on it's own .. first question , is it possible to fix ?? I Mean to replace the fader with a new one ? Cause i heard that the Faders are not replaceable .. only the volume ones can be replaced .. Second question , can i disable the Deck's A Tempo Fader from the Mappers ?? To Fully Freeze the A Fader .. until i find a fix ..
