Frequently asked questions
Can I hum a melody and get MIDI?
Yes. Humming and whistling work well because they produce one clear note at a time. Record in a quiet room and keep the phone close.
Why are some sung notes split or missing?
Strong vibrato, slides between notes and breaths can split a note or hide it. The voice setting merges short fragments, but a steady, clearly sung line gives the best result.
Can it separate the vocals from a song?
No — it transcribes what it hears. For a vocal from a full song, first isolate the vocal with a stem-separation tool, then upload the vocal track.
Is it free? Do I need an account?
Yes, it is free and you do not need an account. Each visitor can convert up to 10 files and download 2 MIDI files per day (UTC). Previewing on the piano roll does not count as a download.
What happens to the files I upload?
Your audio and the MIDI result are used only to run the conversion and are deleted automatically within 48 hours.
Can it turn a full song into MIDI?
A full mix with drums, bass and vocals only gives a rough draft. Splitting a whole song into one MIDI track per instrument is planned as a separate feature.
