Upload the MP3
MP3 is supported up to the active plan size limit. The worker transcribes after the file lands in private storage.
MP3 to MIDI
MP3 to MIDI
An MP3 piano recording can become MIDI after Song2Notation transcribes it into an editable draft. Upload the MP3, review the score, then export MIDI on a paid plan. Useful results still depend on a clean solo piano source.
From MP3 file to MIDI file
Export MIDI when the draft looks usable
Paid plans unlock MIDI. Free preview does not include full exports.
Continue in a DAW
Use MIDI as a starting point for timing, voicing, and arrangement edits. It is not a finished performance.
Supported formats and limits
These limits match the live upload and plan rules. Free is a 30-second preview. Paid plans unlock longer files and MusicXML, MIDI, PDF, Numbered Notation, and Piano Roll access.
File formats
Upload MP3, WAV, M4A, AAC, FLAC, WEBM, MP4, or MOV. Browser recording and supported public YouTube, Instagram, and TikTok links use the same transcription job model.
Plan duration and size
Free previews the first 30 seconds and accepts files up to 25 MB. Pianist allows files up to 6 minutes and 150 MB. Composer allows files up to 15 minutes and 500 MB.
Best source material
Clean solo piano recordings are the strongest fit. Dense mixes, vocals, drums, and noisy audio usually need cleaner input and more human editing.
What the draft is for
Song2Notation generates an AI-editable draft. Export MusicXML to continue in MuseScore, Sibelius, Finale, or Dorico. It is not publication-grade engraving.
