Hi, I Had this issue friday night and had to stop playing video, Basically started the night everything was working fine, then i load a track and when i start mixing, both signal bars on serato go from grey to red and both tunes went really slow and there was digital distortion, when i stopped one of the tracks the other track signal went from red back to grey, i closed mix emergency and it fixed the issue, really strange i can't see how mix emergency can mess with serato dj receiving a control signal!! Anyone else had this issue? owen
