First you need to connect your mixer to your laptop, so that your laptop can receive MIDI messages. Then, in MixEmergency, you'll need to map the mixer's crossfader to the MixEmergency crossfader. To do this: - Enter MIDI mapping mode. (there's a button labelled "MIDI" on the main MixEmergency window) - Click the on-screen control you wish to map. (in this case, the crossfader) - Move or toggle the MIDI control. (in this case, the crossfader) That's it.
