Field notes
The settings distinguish isolated instruments or chords, one melody at a time, and full mixes, which the page labels rough drafts. Tempo controls the MIDI grid rather than estimating the recording’s BPM, while the onset threshold changes how many note candidates are detected. The page says processing stays in the browser and that the first conversion downloads model assets; it also cautions that dense or noisy recordings can produce missing or extra notes.
