Yes, Serato DJ offers MIDI learn functions for adding control from the mixer ... but there's not a lot of controls available on the mixer as the unit operates "audio first" meaning if you map a function to one of the EQ knobs, that EQ knob still affects the audio even though it is sending MIDI signal. If you only ever use 2 channels, you certainly could use the other 2 for MIDI, but you may be better off with another controller dedicated to that kind of control, such as a DDJ-SP1.
