Some users are surprised to learn that connecting certain DJ controllers automatically removes the Virtual DJ logo—even without a paid license. This is because Virtual DJ partners with hardware manufacturers (Pioneer DJ, Numark, Hercules, Denon, etc.). When you plug in a supported controller, Virtual DJ enters “controller unlock” mode, granting you Pro features as long as the controller is connected.
