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.


  • Why some of my notes are red?
  • Those are repetitive notes positioned too close to each other. DIY music boxes won't be able to play them due to technical limitations of the mechanism
  • Is there a physical 60 note music box?
  • 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?
  • Export options are available after publishing
  • Can I set an offset to start playback from a certain point?
  • Yes, there is a context menu on right mouse button
  • I'd like to ask you something else, where can I do it?
  • You are welcome to use our forum
