Audio-to-MIDI Pro turns a complete mix, with no stems or isolated takes, into separate editable parts for the instruments it detects, readable notation, and sheet music you can print.
The latest improvements span the whole workflow in Mirelo Studio: a more accurate transcription model, cleaner chord detection, better playback and review, and more useful score and export options.
What Audio-to-MIDI Pro does
Audio-to-MIDI Pro transcribes a full musical recording into per-instrument MIDI inside Mirelo Studio.
Upload one file and it will:
- detect which instruments are playing and label them
- write a separate MIDI track for each instrument, editable in a piano roll
- detect chords, key, tempo and meter, and carry them into the export
- render the transcription as a score you can read, hear and correct
- export MIDI, MusicXML, and PDF sheet music
Most transcription tools take one sound at a time, which means a single vocal, a solo piano, or one guitar take. Audio-to-MIDI Pro takes the whole arrangement at once.
What is new
Here is what we shipped:
- The model transcribes more accurately. Under the hood, an updated transcription model improves overall note and instrument-assignment accuracy in our evaluations, with the strongest gains on drums.
- Chords are cleaner and more selective. Chord detection is one of the most meaningful user-visible Pro improvements: it is more selective about what it labels, so the harmonic picture in Studio and in the export is easier to trust.
- Scores are ready to use. Instrument-aware clefs, octave placement, and percussion notation make parts easier to read. Export a full score or individual parts as PDF or MusicXML, including supported guitar and bass tablature. PDFs are ready to view, share, and print without notation software.
- Hear and review every part. Switch between the source and MIDI, choose per-instrument sounds, use the detected-beat metronome, and audition notes as you edit.
- Export gives you more control. Choose which instruments to export, preserve performance timing or use one fixed tempo, quantize to the detected beats, adjust the meter, include key and chords, and download MIDI, MusicXML, or rendered audio.
What producers and musicians use Audio-to-MIDI Pro for
Audio-to-MIDI Pro is built around three things musicians do with a finished recording:
- Continue producing from a finished mix. Pull parts out of a recording you already love and take them into your DAW as MIDI. Each instrument arrives on its own track, with the performance's tempo map and meter carried into your session.
- Recreate a recording. Rebuild something old, rare, personal, or generated, with new instruments and full human control. The transcription gives you the musical material. What you voice it with, and what you change, stays your decision.
- See and learn the music. Read, transpose, practise or arrange parts that are hard to transcribe by ear. The score view, the click on the detected beats, and the part PDFs cover the path from listening to playing it yourself.
Get started
A transcription is a starting point you can correct, so the piano roll stays editable and the score follows your edits.
Take a song you know well, run it through Audio-to-MIDI Pro in Mirelo Studio, and open the MIDI in your DAW.
