Common questions
Before you export the MIDI.
Should I split stems before converting to MIDI?
If the source is a finished song, yes. Splitting first gives the converter a cleaner vocal, bass, guitar, piano, or instrumental stem instead of one crowded mix.
Can it isolate the bass, vocals, or piano from a full MP3?
No. Audio-to-MIDI transcription does not isolate instruments. Use 44Stems to separate the track first, then convert the stem that contains the part you want.
Why does a full song create too many MIDI notes?
A full mix contains overlapping vocals, bass, chords, drums, effects, and harmonics. The model may read those layers as extra pitches, so the MIDI can sound busy until you use a cleaner source or adjust the note settings.
Can I preview the MIDI before downloading?
Yes. After conversion you get one synced audio and MIDI timeline, so you can listen once, check the notes, and export the .mid file.
Do I need to choose MIDI settings?
No. The converter automatically tries cleaner and more detailed passes, then picks the best first result. Fine tune is available only if you want fewer notes, more detail, or a tighter pitch range.
Which technology does this use?
The converter uses Spotify Basic Pitch, an open-source audio-to-MIDI model built for pitched musical material and browser-based transcription.
