Macbook pro 15 Touchbar freezes with rekordbox

Hello,

Can somebody with a macbook pro w/ touchbar can tell me if he had any problem with rekordbox, I explain :

My touchbar "freeze" randomly only when I have rekordbox installed on my mac (even if it not launched). Else, I found how to repeat the bug.

When my DJM 850 is connected to my computer, w/ rekordbox open, if I unplug my DJM, touchbar immediatly power off (No touchbar parameters, no process, like a mcb pro without touchbar), and Safari freeze completely.

If I re-connected the DJM to the computer, it stays undetected, and the only way to resolve is reboot by holding power button because the Mac don't want to power off.

Most of time, this bug appears totally randomly, even in party and it's very unconvenient. 

Apple says it's a software probleme and I would like to know if it's general or only my mac.
Thanks a lot for your answers
