Follow these steps to convert your Midi to Mp3 now!

  • Step 1 ► Select a midi file
    Click the button and select a Midi file saved on your computer or phone
  • Step 2 ► Choose a soundfont (optional)
    Soundfonts represent real sounds of musical instruments and they are used to convert your Midi and produce a much more realistic sound than the one produced by your soundcard. Use the Sondfont Test and Comparison Tool to listen to the different sounds produced by each soundfont.
  • Step 3 ► Adjust tempo and tonality (optional)
      
    Use these options to alter your Midi before converting it. By adjusting the Tempo you can make the audio play faster or slower; by transposing it you can increase or decrease the pitch.
  • Step 4 ► Choose Mp3 output quality (optional)

    Higher bitrates corresponds to better quality, but also larger Mp3 files.
  • Step 5 ► Apply advanced audio effects (optional)
    You can apply some classic audio effects to your final Midi file, including Reverb, Chorus and Echo.
  • Step 6 ► Select music genre (optional)
    Please tell us the music genre of your midi, it's useful for our statistics.
  • Step 7 ► Want a quick preview? (optional)
    Mp3 conversion takes time and requires computing resources, it is recommended to test the first 30 seconds and listen to the result before converting the whole file.
  • Step 8 ► Add midi information to our database? (optional)
    We maintain a database of MIdi metadata (not the actual files), you can decide wether to add the information of your Midi or not.
  • Step 9 ► Start conversion
    You're ready to go!
