Hi, I've had my DDJ SR for quite a while now, and boy I been having some problems, first it was my software completely freezing while doing a live set, but then I realized I just needed to update the firmware. Well anyway, the right side of my DDJ SR play/pause button isn't playing when I press it softly. I have to apply a bit of pressure to it in order for it to play. It's really annoying because I want everything to be properly calibrated. Please help.
