+# 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
+
+```python
+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
+
+```python
+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
+
+```python
+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
+
+```python
+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
+
+```python
+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
+
+```python
+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
+
+```python
+# 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
+
+```python
+# 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
+
+```python
+# 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
+)
+```
+

+
+## Parametros por Defecto
+
+| FX | Parametro | Valor Default |
+|----|-----------|---------------|
+| Filter sweep | Frecuencia inicio | 80 Hz |
+| Filter sweep | Frecuencia fin | 1.2 kHz |
+| Reverb tail | Wet % inicio | 0% |
+| Reverb tail | Wet % peak | 40% |
+| Pitch riser | Semitonos inicio | 0 |
+| Pitch riser | Semitonos fin | +12 |
+| Micro-timing | Kick offset | -5 ms |
+| Micro-timing | Bass offset | +8 ms |
+

+
+## 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
+
+```powershell
+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
