Well, first I want to tell you that I think the controller is the problem, I have dedicated hours to work Rekordbox dj without connecting the controller, ie only working on the keyboard and I worked perfectly, I have not had any freezes, besides Here I leave a link where many users also comment on the same problem I have, since I have been posting my problem on this site you have always told me that the problem comes from my Mac, Rekodbox, and many other excuses, the True I think it is the DDJ RX driver or maybe the DDJ R series that has gone bad and did not just recognize it or solve the problem to all affected like me, I think this is a very bad and embarrassing image for Pioneer, being leaders In dj teams, and most unfairly do not respond properly to their customers with a true solution
