Why writers keep melodies as MIDI

Capture the tune you hummed as editable notes, so it can become a part in your arrangement.

A voice memo preserves a moment; MIDI preserves the melody. Once your tune is notes, you can change its key to suit a singer, tidy the rhythm, or hand it to a producer as a part.

Single, clear melodies convert best. If the idea is buried in a mix, separate the vocal first and convert that.

Why writers keep melodies as MIDI

Many songs start as a hummed phrase recorded on a phone. Converting that recording to MIDI keeps the melody in a form you can edit, transpose and play on any instrument.

The conversion runs in your browser and does not cost credits. The result opens in the MIDI editor, where you can fix any notes before exporting.

Conversion happens in your browser without spending credits.

Notes, not just pitch

When melody-to-MIDI helps

Voice-memo songwriting

Turn melodies you sang into your phone into parts you can build on.

Changing the key

Transpose a melody to fit the singer you are writing for.

Sharing with producers

Send a clean MIDI part instead of a noisy memo.

For accurate notes

Sing one line clearly

A single melody without accompaniment converts most reliably.

Tidy slides

Slides and vibrato can appear as extra short notes; merge them in the editor.

Chords are not named

Several notes at once are captured as notes, but chord names are not given.

Melody to MIDI questions

Does conversion cost credits?

No. It runs in your browser for free.

Can it convert a full song?

It can, but results are clearer if you separate the melody first.

Will it tell me the chords?

No. It detects notes, including several at once, but does not name chords.

Can I edit the notes?

Yes. Open the result in the MIDI editor to move, delete and correct notes.

Keep the melody before you forget it
