Using the MIDI wizard I was able to get all the buttons working except for the Library buttons, the Pitch bend buttons and the sync button. Using Baretail I was able to sniff out the MIDI signals, and then programmed the pitch bend and sync buttons using the editor in Mixxx. I couldn't sniff out the signals for the LEDs though. I made note of all the other controls, but since I am unable to write MIDI script (I've been attempting but don't seem to be getting anywhere) I can't actually get it working. But I have the opcodes, ctrls, and values, for the jog wheels, and the library browsing stuff. If someone is able to write script for the controller with that information I would be happy to provide it, along with a copy of the midi file I have thus far.
As for the LEDs, I think the only way we'll get that is from Numark, unless it can be pulled out of the VirtualDJ software that it comes with... It must have a midi file or some type of mapping somewhere, right?
If someone could outline a typical script for a jog wheel I could probably figure out how to write the script. I just can't seem to follow the directions on the wiki. My programming skills stop after basic HTML so figuring this out is tricky, but doable with a bit of help.
