An MXPRJ file is a project created by Native Instruments Maschine 2, a hardware and software digital audio workstation (DAW). It contains project settings, which may include drum kits, instruments, sounds, and effects parameters.

The Maschine 2 is a standalone DAW but is designed to be used with the Maschine controller, which is similar to a drum machine. The MXPRJ file is created by Maschine 2 when a user chooses to save his project. The parameters in the project are meant to be modified, allowing a user to save a project, close the Maschine 2 program, reopen it, load the project, and continue production on his audio project.
