Mixxx only has the flanger right now, but with a script function you can simulate a filter by varying the cutoff frequency of the EQ knobs.
For the LEDs on your controller, your best bet is to contact Numark support and ask for the MIDI spec.
Yeah, getting scratching just right is not easy, unfortunately. I have plans to add something for it into the MIDI wizard but it may have to wait until v1.11.1.
