Why beginners love it
Record a melody on your phone and turn it into notes you can see, fix and play on any instrument.
If you cannot write sheet music, this is a way to keep your melodies. Sing it, convert it, and the notes are saved for later.
It works best with a single voice or instrument. Several notes played at once are picked up, but chords are not named for you.
MIDI is simply a list of notes: which pitch, when it starts and how long it lasts. Turning a recording into MIDI means your hummed or played tune becomes something you can edit like text.
The conversion runs in your browser and is free. When it finishes, you can open the notes in the MIDI editor to tidy them up.
