Aligned with the score
Piano Roll uses the same score data as Sheet Music and Numbered Notation, so measure count and notes agree.
Piano Roll
Piano roll generator
Song2Notation generates a Piano Roll from the same AI transcription draft as the staff score. It is a time-and-pitch check of the notes — useful for rhythm density and hand split — not a separate generator disconnected from the score.
What the Piano Roll shows
Visual timing check
Use it to inspect pitch, duration, and left/right-hand distribution before you export MIDI or MusicXML.
Result-page playback
Synchronized playback lives on completed result pages. Marketing previews do not replace that workspace.
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.
