i already tested the two before buyed my new V4 an i think the V4 is the best one
AVM02 is "like" the new pioneer SMV-1000 that is on the way to the stores, i think is for DJ's that use "video clips" on the set
The V4 is way better for VJing. I dont see much advantage to using Livid's software to control a single V4 unless there's some features I'm not aware of
