To turn a song into MIDI, upload an MP3 or WAV, convert it, then inspect the note events before using the file.
This page does not fetch a song from YouTube or another link. Save an audio file you have permission to use, upload it to the browser converter, download the MIDI, and check what the transcription kept. A complete mix can lose notes when instruments overlap.
What the workflow actually delivers
- Prepare an MP3 or WAV containing the part you want to inspect.
- Upload the file and run the browser conversion.
- Download the MIDI and open it in a MIDI editor or DAW.
- Compare the notes with the recording; treat missing or extra notes as transcription results, not a separated source track.
Measured baseline
In the saved generated four-note melody fixture, the converter wrote four MIDI events with pitches 60, 64, 67 and 72. The silent control wrote zero events. These are controlled fixture results, not a claim that every mixed song will preserve every instrument.
Why a full song can lose notes
When vocals, chords, drums and other instruments overlap, one pitch detector has to decide which frequency belongs to the next note. The downloaded MIDI therefore needs listening and editing. The converter does not separate stems or promise chord-level recovery.
Song to MIDI questions
Can I paste a YouTube URL?
No. Download or export an audio file you are allowed to use, then upload the MP3 or WAV.
Will a full mix become separate instrument tracks?
No. The output is a detected note sequence; it is not stem separation.
How do I check the result?
Open the downloaded MIDI in a DAW or MIDI editor, play it beside the source recording, and remove notes that do not match.
What should I do when the file fails?
Try a supported MP3 or WAV with audible melody, then compare the downloaded result with the silent-control behavior described above.
