Uf Gozal — transcription & rock-band arrangement

Tooling that turns a scanned lead sheet of Uf Gozal (עוף גוזל, Miki Gavrielov / Arik Einstein) into an engraved score and a produced, multi-instrument rock arrangement — all from the command line on Linux.

Source files

File	What it is
oof-orig.pdf	the original scanned lead sheet (input)
uf-gozal-v2.ly	LilyPond transcription: melody + chords, 63 bars, hand-verified against the scan
arrange-band.py	expands the melody+chords into a 10-track rock band (drums, bass, guitars, keys, strings, solo)
mix-studio.py	renders each track to a stem and mixes: EQ, compression, panning, amp-sim on the guitars, reverb, bus glue, mastering to a measured loudness
render.sh	one-shot pipeline: score → arrangement → mix → mp3
omr/	uv project holding the Python deps (mido, numpy, scipy, pedalboard) and the OMR MusicXML the transcription was checked against
STUDIO-SETUP.md	notes on the installed plugin/soundfont studio (Ardour, sfizz, amp sims, etc.)

Build

./render.sh            # full rebuild: score, arrangement, mix, mp3
./render.sh --fast     # reuse cached instrument stems (mix tweaks only)
./render.sh --score-only

Needs lilypond, fluidsynth, ffmpeg, and uv. Python deps live in omr/ — cd omr && uv sync if the venv is missing.

Outputs (all git-ignored, regenerated by the build): uf-gozal-v2.pdf, uf-gozal-band.midi, uf-gozal-band-mixed.{wav,mp3}.

Notes

• The mix is judged by measurement (BS.1770 loudness, true-peak, per-section balance), not by ear — see the header comments in mix-studio.py.
• Guitar tone uses GuitarML neural amp-sim VST3s hosted offline through pedalboard; the solo cascades the amp for heavy distortion.
• Instruments other than the guitars currently render from a General-MIDI soundfont; swapping in the SFZ libraries is the main open improvement.
