Question about Numark Party Mix

The DJ controller in question is compatible with software such as Serato DJ Lite and Algoriddim djay Pro AI, but is not specifically designed to work with FL Studio. FL Studio is a DAW (Digital Audio Workstation) used primarily for music production, whereas the controller is optimised for mixing and DJing. You may have to use third-party software or custom configurations to integrate it with FL Studio, but it is not a native or officially supported solution.
