Midi Out on Rekordbox Doesnt do anything

Is MIDI out for led feedback implemented for 3rd party controllers? I'm trying to get some LED feedback on my x1 and z1 and nothing is happening. Tried a bunch of things here and after looking at midi output in MIDI monitor for os x and Max MSP, it looks like Rekordbox DJ isnt sending anything. Is this intended? or is it supposed to send MIDI for feedback to unofficial controllers. Kind of don't want to waste any more time if this feature doesn't exist. Would be really helpful to get midi feedback Please let me know.

  Also, any info on what the MIDI Codes in the MIDI settings window are? I'm trying to figure out what they stand for. For instance "B028" - i know that the "28" is hex for 40 - which makes sense. curious what the first 2 numbers represent.

 im on rekordbox 4.22 and os x 10.10.5

Thanks
