Last week we launched Audio-to-MIDI Pro, our most accurate MIDI transcription model, built for producers and musicians.
It converts a finished recording into editable MIDI. Upload an MP3 or WAV, and every instrument it hears comes back as its own MIDI track, with no stems and no isolated takes needed.
The track under this video is not stock. We built it with Audio-to-MIDI Pro, from a sample, the same way you would.
We took "Stardew Valley - Winter", pulled the melody and the chords out as separate MIDI parts, and rebuilt them with our own instruments.
Drop an MP3 or WAV into Mirelo Studio. There is nothing to install and no plugin to load.
Audio-to-MIDI Pro takes the full mix, so you do not need to separate stems first. Files can run up to 30 minutes.
It runs in the browser, and the MIDI it returns opens in Ableton, FL Studio, Logic or any other DAW.
Studio detects and labels the instruments it hears, and reads the chords, key, tempo and meter alongside them.
On our launch track that came back as a melody line and a chord part, each on its own MIDI track.
Open the piano roll to see the notes, or the score view to read them.
Audition each part with different sounds, so you are judging the notes rather than a default patch. Fix anything that came back wrong while you are in there.
Export per instrument, or pull a single instrument out on its own. Three formats come out of the same transcription:
Once it’s MIDI, you can take the arrangement in any direction: revoice the parts with new synths, samplers or VSTs. Split a chord across instruments, one note or voicing per sound, or send different chords to different patches. Transpose, reharmonise, rearrange or resample only the ideas you want to keep.
Here is how we finished the launch track.
The melody MIDI went to a Moog, and became the wonky top line that leads it. The chords went into Serum with tape saturation, reverb and chorus, which gave the beat its body.
We pulled more chord ideas from the remaining MIDI parts for the drop, then put a simple trap beat under all of it.
Same notes, but a completely different record.
Take a song you know well, run it through Audio-to-MIDI Pro, and open the MIDI in your DAW.
The same transcription is available through the Mirelo API, if you want MIDI output inside your own product.
Audio-to-MIDI Pro is live now at mirelo.ai/models/audio-to-midi.
