With our online music box melody editor you can create custom music box melodies, share them on the web, export to MP3, MIDI, PDF print outs and play them on DIY paper strip music boxes. The editor supports MIDI file import, so you can use other music software like REAPER, Ableton or Soundtrap to make your melodies. Please check out melody requests page if you need help with making a melody or if you would like to offer help to other users.

  • No, unfortunately it does not exist. This format is intended to be used for online melodies
  • Can I select and duplicate a part of the melody?
  • No, this feature is not available. Please consider making a MIDI file in another app and import it to our editor
  • I don't see any way to download a PDF, where is it?
