# Sprint 7 Implementation Summary

## Implemented Features

### 1. Advanced Sample Rotation System (Fases 11-25)

**File:** `AbletonMCP_AI/__init__.py`

#### Key Components:

**`_initialize_sentimiento_samples()`**
- Scans and classifies 658 samples from SentimientoLatino2025 library
- Categories: 26 kicks, 26 snares, 34 drumloops, 34 percs, 24 fx, 84 oneshots
- Stores samples with metadata (path, name, energy, category, usage tracking)

**`_classify_sample_energy(filename)`**
- Analyzes filenames to determine energy level (0.0-1.0)
- High energy keywords: "hard", "heavy", "intense", "aggressive", "punch", "smash", "distorted", "dubstep", "trap", "banger", "power", "hit"
- Low energy keywords: "soft", "light", "gentle", "smooth", "ambient", "pad", "atmosphere", "calm", "mellow", "chill", "relaxed", "subtle"
- BPM detection from filename for additional energy boost

**`_pick_for_scene(category, scene_name, scene_energy, flags)`**
- Energy filtering:
  - `energy < 0.3`: selects from "soft" samples
  - `energy > 0.8`: selects from "hard" samples
  - `0.3 <= energy <= 0.8`: selects from "medium" samples
- Usage tracking: avoids samples used in previous scene
- Scene flag support:
  - `riser`: prefers riser-type FX samples
  - `impact`: prefers impact/hit/crash samples
  - `ambience`: prefers ambient/atmospheric samples

**`_distribute_samples_across_scenes(target_unique=100)`**
- Ensures minimum 100 unique samples distributed across 13 scenes
- Returns scene-to-samples mapping
- Tracks which scenes have used each sample

### 2. 13 Scenes Configuration (Fases 56-70)

**SCENES Array:**
```python
SCENES = [
    ("Intro", 4, 0.20, {"drums":False, "bass":False, "lead":False, "chords":"intro", "pad":True, "ambience":True}),
    ("Verse A", 8, 0.50, {"drums":True, "bass":True, "lead":False, "chords":"verse_standard", "hat":True, "drum_intensity":0.6}),
    ("Verse B", 8, 0.60, {"drums":True, "bass":True, "lead":True, "chords":"verse_alt1", "hat":True, "drum_intensity":0.7}),
    ("Pre-Chorus", 4, 0.75, {"drums":True, "bass":True, "lead":False, "chords":"prechorus", "pad":True, "hat":True, "riser":True, "anticipation":True}),
    ("Chorus A", 8, 0.95, {"drums":True, "bass":True, "lead":True, "chords":"chorus_power", "pad":True, "hat":True, "impact":True, "drum_intensity":1.0}),
    ("Chorus B", 8, 0.90, {"drums":True, "bass":True, "lead":True, "chords":"chorus_alternative", "hat":True, "drum_intensity":0.95, "modulation":"+1"}),
    ("Verse C", 8, 0.55, {"drums":False, "bass":True, "lead":True, "chords":"verse_alt2", "ambience":True, "variation":True}),
    ("Chorus C", 8, 0.95, {"drums":True, "bass":True, "lead":True, "chords":"chorus_rising", "hat":True, "drum_intensity":1.0}),
    ("Bridge", 4, 0.40, {"drums":False, "bass":True, "lead":False, "chords":"bridge_dark", "pad":True, "ambience":True, "modal_borrow":True}),
    ("Build Up", 4, 0.80, {"drums":True, "bass":True, "lead":False, "chords":"tense", "pad":True, "hat":True, "riser":True, "crescendo":True}),
    ("Final Chorus", 8, 0.95, {"drums":True, "bass":True, "lead":True, "chords":"epic", "pad":True, "hat":True, "drum_intensity":1.0, "all_layers":True}),
    ("Outro", 4, 0.30, {"drums":False, "bass":False, "lead":False, "chords":"outro_resolve", "pad":True, "ambience":True, "decrescendo":True}),
    ("End", 2, 0.00, {"silence":True}),
]
```

**Structure:**
- Total bars: 74 bars
- Energy curve: progressive build from 0.20 to 1.00, then fade to 0.00
- Scene flags control which elements are present:
  - `drums`, `bass`, `lead`: boolean for element presence
  - `chords`: specific progression name
  - `pad`, `hat`, `riser`, `impact`, `ambience`: boolean for specific sounds
  - `drum_intensity`: float 0.0-1.0 for drum pattern density
  - `silence`: special flag for End scene

### 3. Production Command

**`_cmd_produce_13_scenes()`**
- Creates 6 audio tracks (kick, snare, drumloop, perc, fx, oneshot)
- Creates 4 MIDI tracks (dembow, chords, lead, sub bass)
- Loads instruments (Wavetable/Operator)
- Distributes samples across all 13 scenes
- Generates appropriate MIDI patterns based on scene flags
- Supports auto-play and arrangement recording

**MCP Tool:** `produce_13_scenes`
- Exposed in `mcp_server/server.py`
- 5 minute timeout for full 13-scene recording

## Testing

### 1. Health Check
```python
ableton-live-mcp_health_check()
```

### 2. Initialize Samples
```python
# This happens automatically, but can be verified via logging
```

### 3. Produce 13 Scenes
```python
ableton-live-mcp_produce_13_scenes(
    genre="reggaeton",
    tempo=95,
    key="Am",
    auto_play=True,
    record_arrangement=True
)
```

### 4. Check Recording Status
```python
ableton-live-mcp_get_recording_status()
```

### 5. Verify Arrangement
```python
ableton-live-mcp_get_arrangement_clips()
```

## Expected Output

```json
{
  "produced": true,
  "sprint": 7,
  "scenes": 13,
  "unique_samples": 100,
  "tracks_created": 10,
  "samples_loaded": 100,
  "tempo": 95,
  "key": "Am",
  "scene_assignments": {
    "Intro": ["oneshot", "fx"],
    "Verse A": ["kick", "snare", "drumloop", "perc"],
    ...
  }
}
```

## Files Modified

1. `AbletonMCP_AI/__init__.py` - Added:
   - `SCENES` configuration (13 scenes)
   - `_sample_usage_tracker`, `_energy_classified_samples`, `_sentimiento_samples`
   - `_initialize_sentimiento_samples()`
   - `_classify_sample_energy()`
   - `_pick_for_scene()`
   - `_distribute_samples_across_scenes()`
   - `_cmd_produce_13_scenes()`

2. `AbletonMCP_AI/mcp_server/server.py` - Added:
   - `produce_13_scenes()` MCP tool

## Restart Required

After updating `__init__.py`, restart Ableton Live to load the new code:
1. Close Ableton Live
2. Kill any hanging processes
3. Delete CrashDetection.cfg if exists
4. Reopen Ableton Live
5. Verify TCP port 9877 is listening

## Verification

Run these commands to verify implementation:
```powershell
# Check Ableton is listening
netstat -an | findstr 9877

# Test MCP wrapper
python "C:\ProgramData\Ableton\Live 12 Suite\Resources\MIDI Remote Scripts\mcp_wrapper.py"
```
