# Generador ALS - Documentación Técnica
|
|
|
|
## 🎯 Overview
|
|
|
|
El generador ALS es el corazón del sistema. Su función es crear archivos .als válidos programáticamente parseando y generando XML compatible con Ableton Live.
|
|
|
|
## 📋 Estructura de Archivos ALS
|
|
|
|
### Descompresión
|
|
```
|
|
archivo.als (gzip) → XML → Modificación → gzip → nuevo.als
|
|
```
|
|
|
|
### Estructura XML (Ableton Live 12.x)
|
|
|
|
```xml
|
|
<?xml version="1.0" encoding="UTF-8"?>
|
|
<Ableton MajorVersion="5" MinorVersion="12.0_12203" SchemaChangeCount="3" Creator="Ableton Live 12.2" Revision="...">
|
|
<LiveSet>
|
|
<!-- Metadatos del proyecto -->
|
|
<NextPointeeId Value="..."/>
|
|
<OverwriteProtectionNumber Value="..."/>
|
|
|
|
<!-- Tracks -->
|
|
<Tracks>
|
|
<!-- AudioTrack, MidiTrack, ReturnTrack, MasterTrack -->
|
|
</Tracks>
|
|
|
|
<!-- Clips -->
|
|
<Scene>
|
|
<Scene/>
|
|
</Scene>
|
|
|
|
<!-- Automation -->
|
|
<AutomationEnvelopes/>
|
|
|
|
<!-- Devices y efectos -->
|
|
<DevicesList/>
|
|
</LiveSet>
|
|
</Ableton>
|
|
```

|
|

|
'name': 'Bass',
|
|
'midi_pattern': [60, 62, 64, 65],
|
|
'effects': ['saturator']
|
|
}
|
|
]
|
|
}
|
|
|
|

|

|
|
|
|
# El archivo está listo para Ableton Live!
|
|
print(f"Generated: {als_file}")
|
|
```
|
|
|
|
## 🎯 Próximos Pasos
|
|
|
|
1. **Implementar parser completo** - Mapear todos los elementos XML
|
|
2. **Crear templates** - Plantillas para diferentes géneros
|
|
3. **Integrar IA musical** - Análisis y generación más sofisticada
|
|
4. **Sistema de samples** - Base de datos y gestión automática
|
|
5. **Validación robusta** - Verificación de integridad de archivos
|
|
|
|
## ⚠️ Consideraciones Técnicas
|
|
|
|
- **XML Encoding**: UTF-8 siempre
|
|
- **Gzip compression**: nivel 9 (máxima compresión)
|
|
- **File paths**: usar rutas relativas en FileRef
|
|
- **IDs**: mantener secuencia única
|
|
- **Version compatibility**: mayor versión 5 (Live 11+)
|
|
- **Memory**: cargar samples lazily, no en memoria
|
|
- **Threading**: generación asíncrona para múltiples requests
|
