XDJ-XZ Stand alone Beat Clock for lighting

Hi,

my brother and I want to programm a arduino to control our lighting system. The arduino alredy has a DMX output and can control LED stripes with a self designed light controler. Now we want our lights to be synced with the music is playing. The problem is, that I have a XDJ-XZ and I use it in stand alone mode. My XDJ-XZ in MIDI mode with a DJ software is not an option. My question is how to get an information about the BPM or a signal with every beat playing or something like that out of my XDJ-XZ, so that I can programm my lighting to be synced with the music? Hope someone can help me.
