CMake builds engrave with two Python workers and share a disposable page cache under `build/build_common/engraving-cache`. Native and ARM packaging reuse unchanged pages; CI also retains this cache between runs. Music, playback, and catalog validation still run for every generation. Set `VAMP_ENGRAVING_JOBS` (1-16) to adjust concurrency, or set `VAMP_ENGRAVING_CACHE_DIR` to an empty CMake value to disable caching. Direct generator runs can opt in with `--jobs 2 --engraving-cache build/build_common/engraving-cache --progress`.
The build-time pipeline is Soundslice/MuseScore -> `.xml` -> musical model -> part generation -> JSON, engraved PNG pages, generated-tone audio, and a read-only catalog database. Sources in `data/songs/` retain the seven-section performance form. Numbered sources in `data/practice/` (`000.xml` through `366.xml`, as authored) produce one pass each of **acoustic accompaniment**, **electric melody**, and **vocal melody**. Both categories use the authored musical key, with no key variants or key-selection menu. Duplicate titles never merge exercises.
The build-time pipeline is Soundslice/MuseScore -> `.xml` -> musical model -> part generation -> JSON, engraved PNG pages, generated-tone audio, and a read-only catalog database. Sources in `data/songs/` retain the seven-section performance form. Four-digit numbered sources in `data/practice/` (currently `0001.xml` through `0366.xml`; `0000.xml` is also valid) produce one pass each of **acoustic accompaniment**, **electric melody**, and **vocal melody**. Both categories use the authored musical key, with no key variants or key-selection menu. Duplicate titles never merge exercises.
Guitar parts share a theory-based voicing and proximity search over standard tuning, frets 0-20, and a maximum four-fret span excluding open strings. They render standard notation plus generated TAB. Practice sources provide a monophonic melody and optional chord symbols; the vocal part adds deterministic scat syllables without changing rhythm or written register. Acoustic, electric, and vocal parts all sound one octave below their notation, for both songs and practice. Explicit MusicXML instrument transposition is honored once; an unplayable passage fails rather than being shifted to fit.
