Audio → MIDI transcriber

Hum, sing, or play a single-line melody — from the mic or an audio file — and get back a Standard MIDI File (.mid) of the notes. It tracks the pitch with the tuner's detector, decides where each note begins and ends, and writes them out. This is monophonic: one note at a time (a voice, a flute, a bassline) — chords and full mixes are out of scope. Everything runs here; nothing is uploaded.

Deleting a note here is a one-off cleanup for export — it's not remembered if you change a setting above, since that re-analyzes the whole take from scratch.
