How to use Quick MeloScore
Quick MeloScore turns MIDI into vocal melody sheet music. You can add lyrics to get a score with the words under the notes. For now there is no sign-in, and every feature is free. MIDI and lyrics are processed on your device. Automatic key and note-value detection is only a starting point, so check and fix it before you export.
Vocal melody sheet music from MIDI
Choose a MIDI file in your browser, and it is analyzed on your device to produce a score for the vocal melody. Sort the tracks into main melody, harmony, and backing vocals, and fix the key and note values afterward.
Scores with lyrics
Paste your lyrics and they are converted to hiragana, ready to place on the main melody as a first pass. Adjust the placement and wording on the score to finish a melody score with lyrics.
Runs in your browser
No installation or sign-up needed. You edit the score on your device, and save a JSON file to pick up where you left off. Print and PDF are for checking the score. For step-by-step controls, open Help at the top right of the app.
