I have been using Video SL and found out the best way to record my sets are using Mix Emergency. Like cleats above , I am willing to buy it but will I have to start using mix emergency to do my sets instead of VSL ? Also will ME work with serato as a plug in ? I will be producing a recorded Video Dj set for televison every week and looking for the best way to provide the station with a quality recorded video mix . Using a macbook pro .
