Piano learners
Have a recording of a piece you want to learn? Convert it and load the MIDI into a play-along app like Synthesia to watch the notes, slow it down and loop the hard bars.
Convert Piano Audio to MIDI
Record your piano right here, or upload a recording or a song with piano in it, and get an editable MIDI file back. AI piano transcription captures each note, how hard it was played and when the sustain pedal goes down, ready for your DAW, a play-along app like Synthesia, or sheet music.
How it works
Piano to MIDI in three steps
1Step 1
Record or upload your piano
Play into your microphone right on the page, or drop in an MP3, WAV, M4A, OGG or FLAC: a practice take from your phone, a recital recording, the audio out of a digital piano, or a song with piano in it. Files up to 30 MB and 10 minutes.
2Step 2
AI transcribes the piano
Pick Solo piano or Song with piano and convert. AI piano transcription works out every note's pitch, timing and velocity plus the sustain pedal. For a full song, the piano is separated from the mix first.
3Step 3
Preview and download
Play the result back on the piano roll, then download a standard .mid for your DAW, a play-along app like Synthesia, or notation software.
What you get
Piano MIDI that keeps how it was played
A list of pitches alone plays back flat and choppy. This piano to MIDI converter also keeps dynamics and pedaling, so the MIDI sounds closer to the performance you recorded.
Velocity on every note
Each note keeps how hard it was struck, so soft passages stay soft and accents still stand out when you play the MIDI back, instead of every note landing at the same volume.
Sustain pedal included
Pedal presses are written into the MIDI file, so chords and arpeggios ring and blend the way they did in the recording rather than cutting off note by note.
Solo recordings or full songs
A solo take is transcribed directly. For a song with vocals, drums or a band, the piano is pulled out of the mix first, so you only get the piano part.
A .mid that opens anywhere
Download a standard MIDI file for Ableton, FL Studio, Logic or GarageBand, play-along apps like Synthesia, or notation software like MuseScore when you want sheet music.
Who it's for
For anyone who wants the notes behind a piano recording
Learning a piece, transcribing a song or rebuilding a cover: piano to MIDI gives you a draft to start from instead of working everything out note by note.
02
Transcribers & arrangers
Working out a song by ear? Start from a MIDI draft of the piano part instead of a blank page, check the voicings, then clean it up into a lead sheet or a full score.
03
Piano cover creators
Pull the piano part out of a song you want to cover, see the chords and runs on a piano roll, and use the MIDI for falling-notes videos or your own arrangement.
04
Producers & DAW users
Turn a piano sample or your own rough take into MIDI, fix the wrong notes, and swap in a better sound while keeping the original dynamics and pedaling.
FAQ
Piano to MIDI, answered
Upload your piano recording above, choose Solo piano or Song with piano, and press Convert to MIDI. The AI transcribes the piano into MIDI notes you can preview on the piano roll and download as a .mid file. MP3, WAV, M4A, OGG and FLAC all work.
A clear solo recording: just the piano, little background noise and not too much room echo. A phone recording of an acoustic piano or the audio output of a digital piano both work. The cleaner it sounds, the fewer notes you'll need to fix afterwards. You can also record right on this page: put the microphone close to the piano and keep the room quiet.
Yes. Choose Song with piano and the piano is separated from the mix before it's transcribed. This works best when the piano is clearly audible. If it's buried under vocals, guitars or synths, quiet notes and inner voices can be missed, and a few notes from other instruments may slip in. Only the piano comes out: vocals, drums, bass and other instruments are not transcribed.
Yes. Every note carries a velocity value based on how loudly it was played, and the sustain pedal is written into the file, so the MIDI keeps the dynamics and pedaling of the recording. In your DAW you can edit both like any other MIDI data.
Treat it as a strong first draft, not a finished score. Clean solo piano usually comes out close, but very fast runs, dense chords, heavy pedaling and lots of reverb can lead to missed or extra notes. Plan to listen through and fix a few spots in your DAW or notation editor.
Yes. The download is a standard .mid, so it opens in play-along apps like Synthesia, in any DAW, and in notation software like MuseScore or Lacuna's MIDI to sheet music converter. The notes come out as one piano part, so expect to tidy the rhythm and the left and right hand split when you make sheet music; a recorded performance has natural timing and rarely sits exactly on the beat grid.
Each conversion uses credits, and the exact amount is shown next to the Convert button before you start. You can sign up for free: the Free plan includes a monthly credit allowance shared across Lacuna, and paid plans add more. 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.
MP3, WAV, M4A, OGG and FLAC, up to 30 MB and 10 minutes per file. Uploaded audio is kept for 30 days, and your MIDI files stay in your conversion history.
