Deterministic local conversion
MIDI to editable sheet music
Convert a standard MIDI file to an editable score locally, preview and play the notation, and correct quantization, voices, spelling, and layout in the NotationAI editor.
Honest conversion route
A MIDI file records timed performance events, not a fully engraved score. The local converter creates a practical MusicXML starting point, but rhythm quantization, voice separation, enharmonic spelling, notation detail, and layout require musical review.
Convert MIDI into an editable score
Choose a Standard MIDI File. The deterministic conversion runs in the browser and does not send the performance to an AI transcription service.

Source-specific workflow
From MIDI to a checked editable score
The preview is an import test, not proof of perfect fidelity. Complete these steps before treating the converted document as a new source of truth.
- 1
Prepare a clean Standard MIDI File
Use .mid or .midi with clear tracks, a stable tempo map, and minimal accidental overlaps. If you control the source performance, quantized timing and separated instruments improve the starting notation.
- 2
Convert and inspect the local result
The browser score engine turns MIDI events into an engraved MusicXML document. Preview the part count, note count, rhythms, and playback before entering the editor.
- 3
Restore notation intent by hand
Correct measure spelling, tuplets, voices, ties, enharmonics, articulations, dynamics, instrument names, and page layout. Treat the conversion as an editable draft, not an authoritative edition.
What fidelity really means for this route
First confirm musical meaning, then inspect application-specific engraving and playback. A clean preview can still need deliberate editorial correction.
Usually carried
- Performed note pitches, start times, durations, track separation, and tempo events
- Velocity and controller information insofar as the local import can interpret it
- A deterministic, repeatable conversion result that can be downloaded as MusicXML
Verify carefully
- Quantization, tuplets, pickup measures, overlapping notes, and sustain-pedal effects
- Voice allocation, enharmonic spelling, clefs, transpositions, and instrument identity
- Ties, articulations, dynamics, lyrics, chord symbols, repeats, and visual layout
Not promised
- Notation that was never encoded as MIDI events, such as exact articulations or engraving
- Reliable separation of musical voices or intended rhythm from every human performance
- Audio timbre, plugin presets, mixer effects, or a finished publishable page
Questions before you convert
Is MIDI-to-score conversion the same as audio transcription?
No. MIDI already contains symbolic note events, so this tool does not recognize pitches from sound. It converts event timing into notation with deterministic local rules.
Why are the rhythms or voices different from what I played?
Performed timings overlap and deviate from a notation grid. A converter must quantize and group those events without knowing all of the performer’s written intent.
Does MIDI conversion consume an AI quota?
No. The conversion, MusicXML generation, engraving, and preview run locally with the NotationAI score engine. No model request is made.
