jdxi_editor.midi.music.pdf_export

Export a MIDI file to sheet music PDF (music21 + LilyPond) for use by the app menu. Uses the same logic as piano.py for consistent LilyPond behavior.

Functions

short_name(→ str)	Abbreviation for staff label (e.g. 'Piano' -> 'Pno.', long names truncated).
export_midi_to_pdf(→ Optional[str])	Export a MIDI file to a PDF in the same directory (stem.pdf).
cleanup_score(...)	Minimal cleanup with safe quantization.
annotate_staffs(score, track_names)
_ensure_parts_have_measures(→ None)	Ensure every part has at least one Measure so LilyPond export does not hit context bugs.
export_score(→ tuple[pathlib.Path, pathlib.Path])
set_metadata(composer, score, title)
remove_empty_parts(score)	Remove any parts that have no notes, chords, or rests.

jdxi_editor.midi.music.pdf_export.short_name(name: str, max_len: int = 12) → str

jdxi_editor.midi.music.pdf_export.export_midi_to_pdf(midi_path: str | pathlib.Path) → str | None

jdxi_editor.midi.music.pdf_export._ensure_parts_have_measures(score: music21.stream.Score) → None

Ensure every part has at least one Measure so LilyPond export does not hit context bugs.

jdxi_editor.midi.music.pdf_export.export_score(midi_file: pathlib.Path, midi_file_stem: str, score) → tuple[pathlib.Path, pathlib.Path]

jdxi_editor.midi.music.pdf_export.set_metadata(composer: str, score: music21.stream.Score | music21.stream.Part | music21.stream.Opus, title: str)
