source : Yeah, the Behringer DDM-4000 is definitely an option - but, because you can't assign the audio and MIDI to the crossfader at the same time, it is not a mixer that we recommend for use with MixEmergency. I Have the crossfader set to fade the video's and the up sliders to do the audio, this works great for me. i have the 2 inner sliders (2+3) for audio and the 2 outer sliders 1+4) for pitch when in int mode. Basically i dj without cd players or vinyl, all from my mixer ... Good for my pub gigs so i don't have to take my decks/cd players.
