www.agiprodj.com DJ Ty from agiprodj demonstrates the Ecler EVO4 with Serato Video Scratch LIVE. The EVO4 http://www.agiprodj.com/ecler-evo4/ is a 4 Channel 12" Mixer with 2 separate effects processors, and MIDI via USB. MIDI is almost necessary to mix video with Video Scratch LIVE. Using MIDI lets you control the Software Video Crossfade of VSL to be in sync with the audio crossfader. Hard to understand? Just check out the video - it'll all make sense !
