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

Showcases ramp(), articulations, Part.hit(), filter automation,
and cross-genre fusion. 303 acid bass with tabla entering at the
peak and riding through the outro.

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.

- Harmonium: single free reed, nasal midrange, bellows swell.
The sound of kirtan and qawwali.
- Doumbek (darbuka): dum (center bass), tek (edge sharp), ka (muted).
4 patterns: maqsoum, baladi, saidi, ayoub.
2 fills: doumbek roll, doumbek accent.
- 42 synth waveforms total

Tihai (3x crescendo landing on sam), chakkardar (32nd triplet
cascade), tiri kita (rapid 16th dayan burst), bayan (bass bends),
tabla call (dayan/bayan call-and-response).

No more timing gaps. The leading string is held at 15% velocity
at the same beat position as the full chord via hold(), adding
strum texture without stealing time.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
hold() adds a note without advancing the beat position, so the
next note starts at the same time. Enables: piano sustain (bass
rings while melody plays), drone notes under melody, held chords
with moving lines.
Two lines in the renderer: skip beat_pos advance when _hold is set.

Grace notes created audible gap before chord and sounded like
separate plucks. Pure chord hit sounds better.

G-D-Em-C at 120 BPM. Picked intro, strummed verse, electric lead
melody, strings swell, rock drums. The most popular chord progression
in pop history.

Random key, tempo, reverb space, instruments, and melodies.
Melodies walk the scale stepwise (not random jumps), arpeggios
follow chord tones in order, piano walks up/down. Tabla solo
always closes with random strokes. No seed — truly unique each play.

Didgeridoo drone throughout, granular abyss, kalimba light,
cello surfacing, piano + quiet uke, pedal steel + theremin solo
(searching → building → soaring peak), strings/flute/harp/timpani
at the peak, 4-part tabla solo finale (whisper → ghosts → 9-tuplet
call-response → 32nd triplet cascade + grand tihai).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- humanize=0.2 added to all melodic parts (leads, basses, bells)
- Subtle reverb (0.1-0.2) on bass parts that had none
- Per-note velocity dynamics on all leads (was static)
- Blues lead changed from trumpet to saxophone (more fitting)
- Songs 17-18, 20-26 left untouched (already well-crafted)

play(), play_score(), _play_for() now catch Ctrl-C and stop
cleanly instead of crashing with a traceback. CLI demo also
wrapped.

dreams, outback drone, highland, nashville tears, tabla fusion
All new synths represented in pytheory demo random rotation.

- Ukulele: nylon string KS with small body resonance (350/700/1200Hz),
faster decay than guitar, mid-heavy character
- Strum sweep: 2 quiet grace notes (25% vel) before the chord hit,
gives audible strum feel without choppiness
- Default strum_time 0.08 → 0.05 for tighter feel

Polyrhythm section uses musical phrases (ti-ra-ki-ta patterns)
in 5-groups, 7-groups, and 9-groups rather than mechanical grid
overlays. Reverb pulled back to 0.4 across the song.

Orchestral piece in 22-shruti JI with choir vowel pads, timpani
rolls, bansuri, cello, sitar, strings, harp, djembe→tabla→extended
tabla solo finale (whisper→ghosts→call/response→9-tuplets→32nd
triplet cascades→grand tihai→slam).

Formant synthesis: glottal buzz source through parallel bandpass
filters at vowel resonance frequencies. Supports 5 vowels (A E I O U)
with consonant onsets (plosives, sibilants, nasals, fricatives,
liquids, aspirates, glides). Per-note lyrics via Part.add(lyric=).
Best for choir pads — vowel sounds with cathedral reverb and detune.
Consonant synthesis is rudimentary (noise bursts, not real speech).
Presets: vocal (solo), choir (detuned ensemble).

Grain cloud synthesis: source waveform chopped into tiny overlapping
grains (40ms, 50/sec) with Hanning windows, random scatter, and
per-grain pitch variation. Creates textures impossible with other
synthesis. Two presets: granular_pad, granular_texture.
30 synth waveforms total.

Strings, cello, trumpet, clarinet, oboe all cut to 0.001 depth.
Much subtler in ensemble context.

- roll(tone, duration, velocity_start, velocity_end, speed) — rapid
repeated notes with velocity ramp. Works on any instrument.
- Saxophone reed noise boosted and bandpass filtered for more bite
- Timpani preset: cathedral reverb at 0.4

- 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)

B#4 now correctly resolves to C5 (523.25 Hz), not C4 (261.63 Hz).
Cb4 now correctly resolves to B3 (246.94 Hz), not B4 (493.88 Hz).
When an accidental crosses the B/C octave boundary, the octave is
adjusted: sharps crossing B→C increment, flats crossing C→B decrement.
Also handles double sharps (B##→C#5) and double flats (Cbb→Bb3).
Closes#45
