- Keyboard mode is now a proper modal: kbd enters, Esc exits
- All keys go to MIDI while in keyboard mode, Up/Down change octave
- Header shows KBD and REC indicators
- VU meters use ASCII-safe characters
- play_recording.py: render MIDI through full engine

- Tab completes commands, instruments, patterns, fx params
- Left/Right arrows move cursor, insert mid-line
- Home/Ctrl-A, End/Ctrl-E for jump to start/end
- fx <ch> <param> <val> for live effect tweaking
- fx alone lists all params, fx <ch> shows current values

_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.

- Channel validation: ch must be int 1-16, raises ValueError
- Port validation: string port raises ValueError if not found
- Exception-safe MIDI: open_port wrapped in try/except, cleanup on failure
- Reverb CC clears cache (was missing)
- stop() uses _stop_event to unblock start()
- _all_notes_off clears drum channel too
- Sorted __slots__
- Fixed en-dash in docstring
- Documented 3-second wavetable limitation
- Unused loop var fixed

MIDI pitch bend (0xE0) adjusts playback rate of active voices
via linear interpolation through the wavetable. ±2 semitone range.

- MIDI clock (0xF8) tracking for BPM detection
- Start/Stop/Continue transport handling
- engine.drums("rock") plays pattern synced to MIDI clock
- Pre-render all wavetables (MIDI 36-96) on startup for zero-glitch playback

Simple feedback delay network reverb applied during wavetable
rendering. 3 early reflection taps + 6-pass feedback loop for tail.
Extended wavetable to 3 seconds for reverb room.

engine.cc(0, "lowpass", min_val=300, max_val=8000) maps any MIDI CC
to any channel parameter. Supports per-channel or global mapping.
Invalidates synth cache when filter params change.

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.

Ensemble rendering no longer re-synthesizes every note N times.
Renders the part once, then creates N copies with per-player
time shifts and velocity variation (cheap buffer ops).
Benchmarks:
- Heavy (ens=10+effects): 12.7s → 3.0s (4.2x faster)
- Ensemble=20: 4.3s → 0.43s (10x faster)
Also: vectorized strings_wave body_response, synth output cache.

- Wurlitzer: reed-based, nasal, biting — bark on hard hits
- Vibraphone: aluminum bars with motor tremolo (spinning disc)
- Pipe organ: multi-rank (8'+4'+2'), constant air, wind chiff
- Choir: formant-filtered glottal source, vowel control via lyric=,
no vibrato (ensemble handles voice variation)
- All four with instrument presets, audio demos, and docs

CAJON_SLAP is now dry wood crack (no wires). New CAJON_SLAP_SNARE
has the buzzy version for cajóns with snare wires engaged.

Added hand-on-wood transient (lowpassed noise for soft palm feel)
before the box resonance kicks in. Deeper sub, longer air cavity
thump. You hear the hand, then the box.

Click count-off → snare groove with quad sweeps and bass splits →
flams and diddles → buzz roll into big unison hit.

Bass has 180/320Hz box resonance modes. Slap has wood panel
resonance under the wire buzz. Tap has hollow finger-on-plywood.
Everything sounds like hitting a wooden box now.

Teental ends with bayan fill. Keherwa has ge_bend accents throughout
plus a bend-heavy final bar. Chakradar preceded by bayan showcase.

Dagga now booms at 30Hz with sustained sub, wider thump band,
and heavier stick impact. The kind of hit you feel in your chest.

The melodic renderer was choking all signal at each new note,
killing strum/hold resonance. Removed — notes now naturally
overlap and ring out. Banjo lick now uses 16th notes.

Fundamental now decays at 0.6/s instead of 1.5/s — rings long
enough that rapid roll hits stack into a singing 'oooh' resonance.
Upper modes still die fast for the initial thump character.

Clean harmonics with dominant fundamental, gentle upper partials,
and soft finger pluck transient. Much purer, singing tone.

Tine + tonebar + electromagnetic pickup model with bell-like
harmonics, metallic attack transient, and pickup nonlinearity.
electric_piano instrument preset now uses rhodes_synth instead of FM.
FM section updated to show bells. Audio demos for both.

Detects silence below -60dB threshold and trims with 0.2s tail
for natural decay. 69 audio files regenerated.

Basic waveforms now play without envelope shaping so you hear
the raw timbre. Complete Example bass at 1200 instead of 600.
