to_tab(tuning=Fretboard.guitar()) now works, along with bass,
ukulele, mandolin, banjo, and any custom Fretboard with capo.

Three new export methods on Score:
- to_lilypond() — complete LilyPond source files for PDF engraving
- to_musicxml() — MusicXML 4.0 for MuseScore/Sibelius/Finale
- to_tab() — ASCII guitar/bass tablature (also on Part)
All three handle multi-part scores, bass clef detection, tied notes
across barlines, chords, and drum tone filtering.

Notes longer than one measure are split into tied pieces so abcjs
can render them correctly (e.g. 16-beat choir drone becomes four
tied whole notes).

Parts with only drum tones or rests are excluded from ABC output.
Chords correctly recognized as pitched content.

New method converts scores to ABC notation with support for multi-voice,
chords, rests, accidentals, and all durations. Pass html=True for a
self-contained HTML page with abcjs sheet music rendering.

Five new synth waveforms: tape-replay Mellotron (strings/flute/choir
tapes with wow, flutter, saturation, 8s fadeout), hard sync oscillator,
ring modulation, wavefolding, and analog drift VCO with pitch
instability. 14 new instrument presets for Score.part(). Synth kwargs
now pass through play()/save()/_render(). 808 bass envelope fixed
from pluck to piano.

Single tanh was too mild. Now chains preamp gain → power amp clip →
asymmetric rectifier sag for proper overdrive/fuzz character.

Two variants modeling Himalayan singing bowl acoustics:
- Strike: mallet hit with chirp from inharmonic partials, long ring
- Ring: rim-rubbed sustained tone with slow build and beating modes

_Channel now stores and applies: chorus, detune, distortion,
saturation, tremolo, analog, delay, phaser, sub_osc, noise_mix.
TUI fx command: fx <ch> <param> <val> to tweak any effect live.
fx alone lists all available params. fx <ch> shows current values.

Fixes CI failure — rtmidi needs ALSA headers on Linux which
aren't available in the test runner. Now optional: import is
lazy with clear error message if missing.

LiveEngine listens for MIDI input and synthesizes audio in real-time.
Each MIDI channel maps to a pytheory instrument with its own synth,
envelope, and effects. Supports polyphony, voice stealing, and
GM drum channel (10).
Adds python-rtmidi as a dependency.

Replace the numeral package with ~30 lines of int2roman()/roman2int()
in _statics.py. Reduces supply chain surface. Fixes#47.

Smoothly sweep any parameter (lowpass, reverb, distortion, etc.)
from current value to target with linear, ease_in, ease_out, or
ease_in_out interpolation curves.

Part.crescendo(), Part.decrescendo(), Part.swell(), and Part.dynamics()
for velocity ramps and custom curves across note sequences.

Add 6 new drum fills: cajon flam, cajon rumble, cajon breakdown,
metal triplet, metal blast, metal cascade. 27 fills total.

Duration enum now supports multiplication, division, and addition
so expressions like `Duration.WHOLE * 2` work instead of raising TypeError.

- Replace pytuning with 30-line native implementations of EDO,
Pythagorean, and quarter-comma meantone scale generators
- Lazy-load scipy.signal (337ms) — only imported when audio rendering
is actually used, not on theory-only imports
- Removes pytuning and sympy from dependencies entirely
Import time: 0.479s → 0.056s (8.5x faster)
Closes#44

16 dedicated instrument synths, speaker cab sim, analog drift,
strumming with fretboard lookup, dhol/dholak/mridangam/djembe/
metal kit with 22 patterns, 5 new demo moods.

- Drums are real Parts with full effects pipeline
- split=True creates kick/snare/hats/toms/cymbals/percussion Parts
- Sidechain triggers on kick only
- Score.from_midi() imports Standard MIDI Files
- Document split drums workflow

Load any Standard MIDI File into a Score. Zero-dependency parser
handles Type 0 and Type 1 files. Each channel becomes a Part,
channel 10 becomes drum hits. Roundtrip with save_midi works.
