I own Behringer CMD Micro DJ controller. My Djay Pro crashed once during a party I played and 3 times when trying to reproduce the problem at home. Now I can make it crash almost every time. All you need to do is to start loading a song to a deck and then click the same button on a controller a few times or random number of buttons to make it crash instantly. Now when playing I try not to touch the controller when new song is being loaded as a workaround but it’s not great solution.
