If you're using Serato DJ Pro, the mixers and controllers listed here should be compatible with MixEmergency: http://serato.com/dj/hardware

Note: The following list has not been updated for quite some time and is not a list of all mixers that will work with MixEmergency - only ones that users have tested and reported here. I thought I'd start this discussion due to the number of questions/e-mails I get about this topic. I'll also post mixers that are MIDI capable that may not work as expected with MixEmergency under the "MIXERS THAT ARE NOT RECOMMENDED" title. So, if possible, could you post: 1. The mixer you're using. 2. How the mixer connects to your computer (does it need a MIDI hub, or can it be connected via USB). 3. If the mixer works well with MixEmergency (if not, what problems the mixer has). I'll edit/update this first post with all the info.
