Sing into the mic. The metronome sets the grid; whatever pitch you hold in each subdivision gets written down. Your fundamental, drawn against staff positions. Vertical lines are beats; darker ones are downbeats. Dots are pitches committed to the score; a red stem through a dot means it heard a re-attack and wrote a new note rather than tying. Re-attack sensitivity decides whether two same-pitch cells are one held note or two repeated notes. It listens for the dip in volume between them: a note is split when the quietest moment at the boundary falls below this fraction of the note's own loudness. Raise it to split more eagerly, drop it to 0 to never split — everything then becomes one long tied note, as before. Sing repeated notes on separate syllables ("ta-ta") and it works; sing them legato on one vowel and nothing in the signal distinguishes them from a held note. Use headphones — otherwise the click bleeds into the mic. The noise gate ignores anything quieter than the threshold; the tolerance rejects pitches further than that from a real semitone, which cuts slides and scoops.
