Is it possible to directly convert .mp3 audio to .mux format.
Converting MP3 Audio Files directly to Myriad Stand-Alone Music Score (.mp3 to .mux conversion) is possible, even though your options are limited to using the original software.
Use Myriad's Harmony Assistant or Melody Assistant, which should allow users to import MP3 audio files in order to generate MUX files.
