I am using traktor pro 3 with a S2MK3 for a long time. Since a few weeks my music starts to 'glitch' when mixing. I can start mixing for a while but after a random period of time and at different songs the sound starts to change and slow down and the track starts to 'gurgle' (don't know the right translation). I went through the whole internet but could not find a solution. Does anyone knows how to fix this?
