FX Automation Applied

Resumen de Automatizacion de FX Implementada

Sprint: Granular v0.1.40
Tareas: T072-T077
Modulo: Integrado en server.py

---

Resumen Ejecutivo

Se implemento automatizacion de FX para transiciones dinamicas en secciones de tracks reggaeton, incluyendo filter sweeps, reverb tails, pitch risers y micro-timing.

FX Implementados

T072: Filter Sweep Automation

def apply_filter_sweep(
    track_index: int,
    section_start_bar: int,
    section_end_bar: int,
    sweep_type: str = "highpass_up"
) -> str:

Tipos de sweep:

• highpass_up: Sube filtro de graves antes del drop
• lowpass_down: Baja filtro de agudos para breaks

Uso tipico:

• 8 bars antes del drop: low-cut sube de 80Hz a 1.2kHz
• Snap al drop: filtro regresa a 80Hz instantaneamente

---

T073: Reverb Tail Automation

def apply_reverb_tail_automation(
    track_index: int,
    section_start_bar: int,
    section_end_bar: int
) -> str:

Patron de reverb:

• Reverb 0% -> 40% -> 0% para crear espacio en breaks
• Automatizacion de reverb send steerable

Uso tipico:

• Breaks atmos: reverb sube al inicio, baja antes del build
• Vocals: reverb swell antes del drop

---

T074: Pitch Riser Automation

def apply_pitch_riser(
    track_index: int,
    start_bar: int,
    end_bar: int,
    start_semitones: float = 0,
    end_semitones: float = 12
) -> str:

Configuracion:

• Pitch inicial: 0 semitonos
• Pitch final: +12 semitonos (1 octava arriba)

Uso tipico:

• Sintetizadores de textura antes del drop
• Noise sweeps con pitch rise
• Snare rolls con pitch creciente

---

T075: Micro-Timing Push

def apply_micro_timing_push(
    track_index: int,
    kick_offset_ms: float = -5,
    bass_offset_ms: float = 8,
    apply_to_clips: bool = True
) -> str:

Offsets tipicos:

• Kick: -5ms (adelantado, "push")
• Bass: +8ms (atrasado, "siente")

Efecto:

• Crea groove organico tipo hardware
• Evita rigidez de cuantizacion perfecta

---

T076: Groove Template Application

def apply_groove_template(
    section: str,
    template_name: str = "tech_house_drop"
) -> str:

Templates disponibles:

• tech_house_drop: Groove apretado, sidechain pronunciado
• tech_house_break: Mas swing, espaciado
• deep_house_drop: Groove suelto, shuffle suave
• techno_minimal: Preciso, casi straight

---

T077: Transition FX Injection

def inject_transition_fx_detailed(
    fx_type: str,
    position_bar: int,
    intensity: str = "medium"
) -> str:

Tipos de FX:

• riser: Ascenso de tension
• crash: Impacto en transicion
• snare_roll: Rollde snare crescendo
• noise_sweep: Barrido de ruido blanco
• reverse: Reverb inverso

---

Integracion con Estructura Reggaeton

Intro (0-32 beats)

• Sin FX automation
• Layer basico: kick, hat, bass

Build A (32-64 beats)

• Filter sweep: highpass up desde bar 56
• Pitch riser: +6 semitonos en ultimos 8 bars
• Reverb tail creciendo

Drop A (64-128 beats)

• Snap de filtros al inicio
• Micro-timing: kick -5ms, bass +8ms
• Groove template: tech_house_drop

Break (128-160 beats)

• Reverb swell: 0% -> 40% -> 0%
• Filter sweep: lowpass down
• FX: reverse reverb antes del build

Build B (160-192 beats)

• Pitch riser: +12 semitonos
• Noise sweep
• Snare roll crescendo

Drop B (192-256 beats)

• Snap de filtros
• Groove template aplicado
• Maximum energy

Outro (256-288 beats)

• Filter sweep: lowpass down
• Fade de elementos

Ejemplos de Uso

Filter Sweep Pre-Drop

# Aplicar filter sweep 8 bars antes del drop
result = apply_filter_sweep(
    track_index=6,  # Synth track
    section_start_bar=56,  # Bar 56 de 64
    section_end_bar=64,
    sweep_type="highpass_up"
)

Reverb Tail en Break

# Reverb automation en break
result = apply_reverb_tail_automation(
    track_index=8,  # Atmos track
    section_start_bar=128,
    section_end_bar=160
)

Pitch Riser en Build

# Pitch riser 1 octava en build B
result = apply_pitch_riser(
    track_index=6,  # Synth track
    start_bar=160,
    end_bar=192,
    start_semitones=0,
    end_semitones=12
)

Reverb tail	Wet % inicio	0%
Reverb tail	Wet % peak	40%
Pitch riser	Semitonos inicio	0

Validacion

Checklist de FX

• Filter sweep sube antes del drop
• Reverb swell en breaks
• Pitch riser en builds
• Micro-timing en drops
• Transition FX en puntos clave

Tests

python -m pytest "tests/test_fx_automation.py" -v

---

Limitaciones

1. Solo MIDI tracks: La automatizacion de audio requiere clips existentes
2. Timing preciso: Los FX dependen de estructura correcta
3. Dispositivos: Solo funciona con dispositivos que exponen parametros

Roadmap

• T078: Automatizacion de compresor sidechain
• T079: Automatizacion de EQ dinamico
• T080: Morphing de presets
