The mmlp file extension is associated with Music Macro Language, a music description language used to compose music on computers and video game systems.
An mmlp file contains composed music in MML and serves as a project file for Macrotune. The software can interpret the MML data for editing or playback.
Macrotune is available for multiple platforms. The mmlp format is intended for use with that software rather than as a general-purpose audio format.
Open an mmlp file with Macrotune. Install the version of Macrotune for the platform in use, then open the file from the program.
An mmlp file is a Music Macro Language project, so it is not normally converted directly like a standard audio file. Open it in Macrotune, which may be able to export the file to another format.
