Scribe — BASE Station score engine

Audio → lead sheet (ABC with chord symbols), MIDI, and timed key / chord / section annotations. Built only from permissively licensed components so output is commercially usable:

Stage	Component	Licence
Notes → MIDI	Spotify Basic Pitch	Apache-2.0
Beats / downbeats / tempo / meter	CPJKU beat_this (`final0`)	MIT
Chords (170-class vocabulary)	BTC-ISMIR19 large-voca	MIT
Key, song sections	librosa + in-house code	ISC
ABC lead sheet	in-house writer	—

Endpoints:

POST /transcribe — multipart file or form audio_url (https), optional melody_only, title
GET /health — per-component load state

Section labels (A, B, C…) mark repeated material; they are not verse/chorus names. Melody is a skyline of the transcribed notes — most accurate on a vocal or lead stem.
