Unfortunately the Allen & Heath Xone:43C mixer is not able to send MIDI signals to Serato DJ Pro for Crossfader and EQ control. Because of this, you will not be able to use the crossfader to fade between videos or use EQ based video effects when using Serato Video.

The current alternative is to use the channel faders to mix your videos with the LINK button activated in the Serato Video panel. You could also connect a secondary, dedicated MIDI controller to further control Serato Video and expand your performance.
