# FL Control — Reggaeton Production System

Python system for generating complete reggaeton `.flp` projects for FL Studio from the command line, using intelligent sample selection and algorithmic composition.

## Features

- **Forensic Sample Analyzer** — 4-layer audio analysis (signal, perceptual, musical, timbre) using aubio
- **Intelligent Sample Selector** — scores samples by key compatibility (circle of fifths), BPM proximity, and character
- **Melodic Generators** — reggaeton-idiomatic patterns: bass tresillo, melodic hooks, chord blocks, sustained pads
- **FLP Builder** — assembles valid FL Studio project files from a JSON song definition
- **MCP Server** — 28-tool Model Context Protocol server for AI-assisted production

## Quick Start

```bash
pip install -r requirements.txt

# Analyze your sample library
1_ANALIZAR.bat          # or: python src/analyzer/__init__.py

# Compose a track
python scripts/compose_track.py --key Am --bpm 95 --bars 8 --output output/track.flp
# or double-click:
COMPONER.bat
```

```

## System Requirements

- Python 3.10+
- FL Studio (for opening generated `.flp` files)
- ~4GB disk space for sample library (not included)

## Workflow

1. Drop your sample library into `librerias/`
2. Run `1_ANALIZAR.bat` to build the sample index
3. Run `COMPONER.bat` to generate a track

## Architecture

The system uses a JSON `SongDefinition` as the single source of truth decoupling composition logic from FLP binary rendering. See `.sdd/` for full technical specs and design documents.
