Convert Vocals to MIDI

Sing or hum straight into your microphone, upload a voice memo, or bring a finished song. Lacuna's AI follows the vocal melody and writes it as a single-line MIDI file you can check on the piano roll, then drag into your DAW and put on any instrument.
How it works

Voice to MIDI in three steps

1Step 1

Record or upload

Sing or hum into your microphone right on the page, or drop in an a cappella take, a voice memo from your phone, or a full song. MP3, WAV, M4A, OGG or FLAC, up to 30 MB and 10 minutes.

2Step 2

AI follows the melody

Pick Just vocals for a voice-only recording, or Full song if there's music behind the singer and the AI will pull the lead vocal out first. It then tracks the pitch and writes each sung note as MIDI.

3Step 3

Preview and drag it into your DAW

Play the melody back on the piano roll to check it against your recording, then download a standard .mid with a single melody track.

What you get

Built for one voice and one melody

Voice to MIDI set up for how people actually capture ideas: a quick take on a phone, a hummed hook, or the vocal of a song you want to rework.

Singing, humming or a voice memo

Record straight from your microphone, or upload an a cappella take, a hummed line or a voice memo from your phone. iPhone Voice Memos save as M4A, which works as is, along with MP3, WAV, OGG and FLAC. No exporting or converting first.

The vocal from a full song

Got a track with music behind the singer? Choose Full song and the AI separates the lead vocal from the instruments, then transcribes only the voice. No trip through a separate stem splitter.

One clean melody line

Voices waver and slide between notes. The converter keeps one note at a time and leaves out slides and bends, so you get a tidy single-track melody that sounds right on a synth lead, piano or strings, and reads cleanly as notation.

Piano roll preview, standard .mid

Play the result on the built-in piano roll and compare it with what you sang. Then download a standard MIDI file for Ableton, FL Studio, Logic, GarageBand or MuseScore.
Who it's for

For anyone whose ideas start as a voice

Songwriters, producers and singers who can hear the melody but don't want to play it in note by note.

01

Songwriters

Turn the melodies piling up in your voice memos into MIDI, then build chords and an arrangement around them in your DAW.

02

Beatmakers & producers

Hum a hook or a topline, convert the hum to MIDI, and put it on a synth lead, a pluck or a bass patch instead of finding it on the keys.

03

Remixers

Pull the vocal melody out of a song as MIDI to double it with a synth, write a counter-melody, or flip it into an instrumental.

04

Singers & music students

Sing a line you can't play on an instrument and see the actual notes. Open the MIDI in MuseScore to write it out as sheet music.

FAQ

Vocals to MIDI, answered

Upload your recording to the converter above, choose Just vocals for a voice-only take or Full song if there's music behind the singer, and hit Convert to MIDI. Lacuna's AI follows the pitch of the voice and writes each note as MIDI. Check the result on the piano roll, then download the .mid and drag it into your DAW.

Yes. Hum or sing straight into your microphone on this page, or upload a phone voice memo. Humming and singing on “la” or “doo” both work. iPhone Voice Memos save as M4A, which you can upload directly. For the cleanest result, record close to the mic in a quiet room. If a guitar or piano is playing along, choose Full song so the voice is separated out before it's converted.

Yes. Choose Full song and the AI first separates the lead vocal from the instruments, then transcribes it. Because that adds a separation step, a full song uses more credits than a voice-only recording. Backing vocals and ad-libs that sit close to the lead can come through and add a few extra notes.

It does best on one clear voice: a dry solo take, a hummed line or a clean lead vocal. Harmonies, choirs, doubled vocals and heavy reverb or delay give it more than one pitch to follow, so notes can jump between voices. Wide vibrato and fast runs can come out as a few short notes. Treat the MIDI as a fast starting point: you'll usually quantize it and fix a handful of notes in your DAW.

A melody is easiest to work with when it plays one note at a time, so the converter keeps a single note at each moment and leaves out slides, scoops and pitch bends. That makes the line simple to re-voice on any instrument or turn into sheet music. The expressive pitch movement of the performance isn't kept, so if a slide matters, add a pitch bend by hand in your DAW.

No. Vocals to MIDI captures pitch and timing only, and the words aren't part of the MIDI file. You'll see the rhythm of the melody on the piano roll, but not the text.

Yes. Choose Record your voice, sing or hum into your computer or phone microphone for up to 5 minutes, then stop and convert. Record close to the mic in a quiet room for the cleanest notes. It isn't a real-time plugin: the MIDI is made after you stop recording. You can also upload a take from your DAW or a phone app: MP3, WAV, M4A, OGG and FLAC are supported, up to 30 MB and 10 minutes.

Each conversion uses credits from your Lacuna balance, and the amount is shown next to the Convert button before you start, so you know the cost first. A full song uses more than a voice-only recording because of the extra separation step. You can try it with the free credits that come with a Lacuna account. Converting and playing the result on the piano roll are covered by credits; downloading the MIDI, MP3 or WAV file needs a paid plan or a one-time export for that conversion.
