+# Sprint 6: Professional Session View Production
+
+## Goal
+Transform `_cmd_build_song` from basic sample rotation into a professional
+Session View production system. All work is Session View only — the user
+records to Arrangement View manually with F9.
+
+## Current State (Sprint 5)
+- 11 tracks (7 audio + 4 MIDI)
+- 5 scenes (Intro, Verse, Chorus, Bridge, Outro)
+- Simple modulo sample rotation (2 samples per category)
+- No velocity/energy variation across scenes
+- No transition fills between sections
+- No pad/texture layers
+- Fragile Session→Arrangement recording
+
+## Sprint 6 Changes
+
+### Module 1: Expanded Track Layout (14 tracks)
+Audio (9):
+1. Drum Loop - Full groove loop
+2. Kick - One-shot
+3. Snare/Clap - One-shot
+4. HiHat - One-shot
+5. Shaker/Perc - Additional percussive layer
+6. Perc Loop - Percussion loop
+7. Bass Audio - Bass sample loop
+8. FX - Risers, impacts, transitions
+9. Ambience - Atmospheric textures
+
+MIDI (5):
+10. Dembow - Wavetable (4 variations per scene)
+11. Chords - Wavetable (8 different progressions)
+12. Lead - Operator (density varies by energy)
+13. Sub Bass - Operator (4 styles per scene)
+14. Pad/Texture - Wavetable (sustained chords)
+
+### Module 2: 8 Scenes with Energy Profiles
+| Scene | Name | Bars | Energy | Elements |
+|-------|------|------|--------|----------|
+| 0 | Intro | 4 | 0.30 | pad + ambience + hi-hats |
+| 1 | Verse A | 8 | 0.60 | drums + bass + chords + dembow |
+| 2 | Verse B | 8 | 0.65 | all verse + lead melody |
+| 3 | Pre-Chorus | 4 | 0.75 | build + riser FX + pad |
+| 4 | Chorus A | 8 | 0.95 | full energy, all elements + impact |
+| 5 | Chorus B | 8 | 0.90 | chorus variation, different patterns |
+| 6 | Bridge | 4 | 0.40 | breakdown, bass + pad + ambience |
+| 7 | Outro | 4 | 0.20 | pad + ambience fade |
+
+### Module 3: Per-Scene Sample Swapping
+- `_pick_for_scene()`: distributes ALL available samples across 8 scenes
+- Each scene gets a different sample from each category
+- Energy-based: softer samples for intro/bridge, punchy for chorus
+
+### Module 4: Energy-Based Velocity
+- `_velocity_range(energy)`: maps 0.0-1.0 to MIDI velocity ranges
+- Intro: vel 70-80, Verse: 85-100, Chorus: 95-127, Bridge: 60-80, Outro: 50-70
+- Applied to all MIDI pattern generation
+
+### Module 5: Better MIDI Patterns
+- Dembow: 4 variations (minimal, standard, double, triple) mapped to scene energy
+- Chords: 8 different progressions across scenes
+- Bass: 4 styles (sub, standard, staccato, slide/melodic)
+- Lead: density scales with energy (0.5-0.8)
+- Pad: sustained triads with whole-note durations
+
+### Module 6: Humanization
+- Applied to all 5 MIDI tracks after generation
+- Instrument-specific profiles (kick=5ms, snare=10ms, hats=15ms)
+- BPM-aware timing conversion
+
+### Module 7: Transition FX
+- Pre-Chorus scene gets FX clip (riser)
+- Chorus A scene gets FX clip (impact)
+- Bridge scene gets ambience clip (downlifter feel)
+
+## Removed
+- `_start_translate_to_arrangement` call (user does F9 manually)
+- `_translate_tick` still exists but not triggered by build_song
+
+## Files Modified
+- `__init__.py`: `_cmd_build_song` rewritten (lines 5342-5705)
+
+## Testing
+1. Health check (5/5)
+2. Run `build_song`
+3. Verify 14 tracks created
+4. Verify 8 scenes with clips
+5. Fire each scene and listen
+6. Press F9 to record to Arrangement

+# 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}),

+- 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
+

-## Architecture
+## Project Overview
+
+**AbletonMCP_AI** is an AI-powered music production system that lets you create complete professional tracks in Ableton Live using **natural language prompts only**. It uses the Model Context Protocol (MCP) to bridge AI agents with Ableton Live's Python API.

+### Session View First Workflow (v3.1)
+
+Primary production workflow:
+
+1. **Generate in Session View:**
+   ```python
+   ableton-live-mcp_produce_13_scenes(
+       genre="reggaeton",
+       tempo=95,
+       key="Am"
+   )
+   ```
+
+2. **Verify MIDI instruments loaded:**
+   ```python
+   ableton-live-mcp_validate_session()
+   # If needed: ableton-live-mcp_fix_session_midi_tracks()
+   ```
+
+3. **Test scenes:**
+   ```python
+   ableton-live-mcp_fire_scene(scene_index=4)  # Jump to Chorus
+   ableton-live-mcp_start_playback()
+   ```
+
+4. **Record to Arrangement (manual):**
+   - User presses **F9** in Ableton Live
+   - Or use: `ableton-live-mcp_record_to_arrangement(duration_bars=70)

+
+## Development Conventions
+
+### Coding Style
+- **Python 3.7+** compatible (uses `from __future__ import` for Python 2/3 compatibility in `__init__.py`)
+- **All-in-one `__init__.py`** - Ableton's discovery mechanism only reads this file, so all Remote Script code lives here
+- **One TCP connection per command** - MCP server opens a new TCP connection to Ableton for each tool call, sends JSON, gets response, closes
+- **No `request_refresh()` in `update_display()`** - Causes CPU loop that blocks Ableton
+
+### File Organization
+- `__init__.py`: ONLY Ableton Live API code (ControlSurface subclass)
+- `mcp_server/server.py`: ONLY MCP tool definitions and TCP client logic
+- `mcp_server/engines/`: Music logic (sample selection, generation, mixing)
+- **No cross-imports** from `__init__.py` into engines (Ableton's Python environment is isolated)
+
+### Testing Practices
+- Always compile-check after edits: `python -m py_compile "<file>"`
+- Run `health_check()` after Ableton restart to verify connectivity
+- Test new tools individually before integrating
+- Use `netstat -an | findstr 9877` to verify TCP port availability
+
+### Error Handling
+- **No silent failures** - Errors must be explicit and actionable
+- **Musical timing** - All timing uses bars/beats, not wall-clock
+- **Coherence scoring** - Sample compatibility threshold at 0.90+

 ## Sample Library
- **Location**: `libreria/reggaeton/`
- **509 indexed samples** in kick/, snare/, bass/, fx/, drumloops/, oneshots/, etc.
+
+### Location
+- `libreria/` - User's raw samples (git-ignored, READ-ONLY)
+- `librerias/` - Organized/analyzed samples (git-ignored, READ-ONLY)
+
+### Expected Structure
+```
+libreria/reggaeton/
+├── kick/
+├── snare/
+├── hihat/
+├── bass/
+├── chords/
+├── melody/
+├── fx/
+└── drumloops/
+```
+
+### Metadata Store
+- SQLite database at `AbletonMCP_AI/mcp_server/engines/sample_metadata.db`
+- 800+ total samples (735+ analyzed with BPM, key, spectral features)
+- **SentimientoLatino2025 collection**: 658 samples (26 kicks, 26 snares, 34 drumloops, 34 percs, 24 fx, 84 oneshots)
+- Librosa-powered BPM analysis for accurate tempo detection
+- Spectral embeddings (MFCC) for coherence matching
+- Analysis cached on first scan, reused forever
+
+## Key Skills
+
+### Skill 1: Reinicio Correcto de Ableton
+**File:** `AbletonMCP_AI/docs/skill_reinicio_ableton.md`
+
+3-step process to cleanly restart Ableton:
+1. Kill all Ableton processes
+2. Delete recovery files (`CrashRecoveryInfo.cfg`, `CrashDetection.cfg`, `Undo.cfg`)
+3. Start Ableton + verify TCP 9877
+
+**When to use:** After modifying `__init__.py`, when changes don't reflect, after crashes.
+
+### Skill 2: Producción Senior de Audio
+**File:** `AbletonMCP_AI/docs/skill_produccion_audio.md`
+
+Professional production workflow with 5 automatic injection methods:
+- M1: `track.insert_arrangement_clip()` (Live 12+ direct)
+- M2: `track.create_audio_clip()` (Live 11+ direct)
+- M3: `arrangement_clips.add_new_clip()` (Live 12+ API)
+- M4: Session → `duplicate_clip_to_arrangement` (legacy)
+- M5: Session → Recording (universal fallback)
+
+**Zero manual configuration** - System chooses automatically.
+
+### Skill 3: Session View Máster (Sprint 7)
+**Status:** ✅ Completed 2026-04-13
+
+Complete Session View production system:
+- **13 scenes**: Intro → Verse A/B/C → Pre-Chorus → Chorus A/B/C → Bridge → Build Up → Final Chorus → Outro → End
+- **20 tracks**: 14 audio + 6 MIDI (Kick layers, Snare layers, Drum Loop, Piano/Chords, Lead, Bass)
+- **100+ samples**: Unique per scene with energy-based selection
+- **BPM coherence**: Librosa analysis + spectral embeddings
+- **Humanization**: Per-instrument profiles with timing/velocity variation
+- **Warp automation**: Complex Pro for non-matching samples
+
+**Usage:**
+```python
+ableton-live-mcp_produce_13_scenes(
+    genre="reggaeton",
+    tempo=95,
+    key="Am",
+    auto_play=True
+)
+# Then press F9 in Ableton to record to Arrangement
+```

+
+## Known Issues & Workarounds
+
+### Issue 1: MIDI Instrument Loading (Async Timing)
+**Status:** ⚠️ Workaround available  
+**Problem:** `browser.load_item()` is asynchronous; devices may not appear immediately after call  
+**Fix Applied:** Polling loop with 3-second timeout, 15 attempts × 200ms  
+**Workaround:** If automatic loading fails, use `insert_device` manually or verify in Ableton UI  
+**Note:** Track will show `device_count=0` until instrument actually loads
+
+### Issue 2: analyze_library Cache Attribute
+**Status:** ✅ Fixed  
+**Problem:** Typo in server.py line 738: `analyzer._cache_file` vs `analyzer.cache_path`  
+**Fix:** Corrected to `analyzer.cache_path`  
+**Verification:** `analyze_all_bpm` tool now functional
+
+### Issue 3: Drum Loop BPM Mismatch
+**Status:** ✅ Auto-handled  
+**Problem:** "100bpm gata only drumloop" vs project at 95 BPM  
+**Solution:** `warp_clip_to_bpm` automatically applies Complex Pro warp mode  
+**Result:** Seamless tempo matching without pitch shift artifacts
+
+## Troubleshooting
+
+| Problem | Solution |
+|---------|----------|
+| Connection refused | Check Ableton has AbletonMCP_AI loaded in Preferences → Link/Tempo/MIDI → Control Surfaces |
+| Port 9877 blocked | Run: `netstat -an \| findstr 9877` |
+| Changes not reflecting | Restart Ableton (delete `CrashRecoveryInfo.cfg` first) |
+| Sample selection empty | Verify `libreria/reggaeton/` has .wav files |
+| Timeout on generation | Check Ableton log for errors |
+| MCP server won't start | Run `mcp_wrapper.py` manually to see error output |

+## 🗺️ Roadmap & Future Work (TODO)
+
+### **Critical Priority (Sprint 8)**
+
+#### 1. MIDI Instrument Loading - Robust Solution
+**Status:** ⚠️ Partial - Polling implemented but unreliable  
+**Problem:** `browser.load_item()` is async, no callback when device actually loads  
+**Current workaround:** 3-second polling loop  
+**Needed solution:**
+- [ ] Implement device presence verification with retry logic (10 attempts × 500ms)
+- [ ] Add fallback: if Wavetable fails, try Operator, then Analog, then Simpler
+- [ ] Create "Instrument Rack" preset approach - load rack with default chain
+- [ ] Alternative: Use `live.object` API if available for direct device creation
+- [ ] Max for Live bridge (last resort) - create M4L device that receives OSC commands
+
+**Acceptance Criteria:**
+- `insert_device` returns `device_inserted: true` AND `device_count > 0` in track
+- Works for: Wavetable, Operator, Analog, Electric, Tension, Collision
+- Max 5 seconds total wait time
+
+#### 2. BPM Analyzer Integration
+**Status:** ✅ Engine created, NOT integrated into production pipeline  
+**Files ready:** `bpm_analyzer.py`, `spectral_coherence.py`  
+**Integration needed:**
+- [ ] Run `analyze_all_bpm()` on full library (800 samples) - takes ~30 min
+- [ ] Store results in `metadata_store` table `samples_bpm`
+- [ ] Modify `produce_13_scenes` to use BPM-coherent samples by default
+- [ ] Add `force_bpm_coherence` parameter to all production tools
+- [ ] Create `get_bpm_recommendations()` tool for user queries
+
+**Acceptance Criteria:**
+- All 800 samples have BPM in database
+- Producing at 95 BPM uses only 90-100 BPM samples (±5 tolerance)
+- Samples outside tolerance auto-warp with Complex Pro
+
+#### 3. Single Drum Loop Architecture
+**Status:** 📝 Planned  
+**Current:** Multiple drum loops rotate across scenes  
+**Desired:** ONE drum loop stretched 1:30 min + harmony variations  
+**Implementation:**
+- [ ] Create `extend_loop_to_duration()` function
+- [ ] Use `clip.loop_end` to extend without re-triggering
+- [ ] Disable sample rotation for drumloop category
+- [ ] Add harmony layers (piano, pads) that change per scene
+- [ ] Keep drum loop constant, vary harmony/progressions
+
+**Acceptance Criteria:**
+- Single drum loop plays continuously for full song duration
+- Harmony/progressions change per scene (Intro≠Verse≠Chorus)
+- No audible cuts/glitches in drum loop
+
+---
+
+### **High Priority (Sprint 9)**
+
+#### 4. Max for Live Integration (Optional)
+**Status:** 📋 Evaluated, not implemented  
+**Use case:** If Python `browser.load_item()` remains unreliable  
+**Approach:**
+- [ ] Create simple M4L device "InstrumentLoader" that listens to OSC
+- [ ] Python sends OSC message: `/loadinstrument track_index, instrument_name`
+- [ ] M4L device uses `live.object` to insert device directly (more reliable)
+- [ ] M4L confirms back via OSC when done
+
+**Pros:** More reliable device insertion  
+**Cons:** Requires M4L license, additional complexity  
+**Decision:** Only implement if Python solution fails consistently
+
+#### 5. Arrangement Recording Automation
+**Status:** 📝 Planned - Currently manual (F9)  
+**Goal:** Auto-record Session View to Arrangement  
+**Implementation:**
+- [ ] `arrangement_overdub` + scene firing + time-based stop
+- [ ] Or: `duplicate_clip_to_arrangement` for each clip (if API available)
+- [ ] Create `auto_record_session(duration_bars=70)` tool
+- [ ] Post-recording: verify all clips appeared in Arrangement
+
+**Current workaround:** User presses F9 manually
+
+---
+
+### **Medium Priority (Backlog)**
+
+#### 6. Advanced Warp Modes
+- [ ] Auto-detect best warp mode (Complex Pro vs Beats vs Tones)
+- [ ] Per-sample warp configuration stored in metadata
+- [ ] Real-time warp quality monitoring
+
+#### 7. Vocal Placeholder Tracks
+- [ ] Create empty audio track labeled "VOCALS" for user recording
+- [ ] Add sidechain ducking from vocals to music
+- [ ] Pre-configure compressor for vocal riding
+
+#### 8. Stem Export Automation
+- [ ] `render_stems()` with track groups (Drums, Bass, Music, FX)
+- [ ] Individual stems + mixed stem option
+- [ ] Naming convention: `ProjectName_StemName.wav`
+
+#### 9. Reference Track Matching
+- [ ] Finish `produce_from_reference()` implementation
+- [ ] Spectral analysis of reference vs generated
+- [ ] Auto-adjust EQ/compression to match reference
+
+#### 10. Batch Production
+- [ ] `batch_produce(count=5)` - Generate 5 variations of same prompt
+- [ ] Each with different random seed for samples
+- [ ] Compare and rank by coherence score
+
+---
+
+### **Bug Fixes Needed**
+
+| Bug | Severity | Status | Notes |
+|-----|----------|--------|-------|
+| `device_count` stays 0 after `insert_device` | **Critical** | Workaround | Polling helps but not 100% |
+| `analyze_library` needs OpenCode restart | Low | Fixed | Cache path typo corrected |
+| Humanization needs numpy | Medium | Broken | `apply_human_feel` fails without numpy |
+| Time stretch clip API mismatch | Medium | Broken | Signature mismatch in `get_notes` |
+| `duplicate_project` renames tracks weirdly | Low | Working | Cosmetic issue only |
+
+---
+
+### **Performance Optimizations**
+
+- [ ] Parallel sample analysis (4 threads for 800 samples)
+- [ ] Lazy loading of heavy engines (librosa, sklearn)
+- [ ] Cache embeddings as binary blobs not JSON
+- [ ] Incremental BPM analysis (only new samples)
+
+---
+
+### **Documentation TODO**
+
+- [ ] Create `docs/sprint_8_midi_loading.md` - Technical deep dive
+- [ ] Create `docs/sprint_8_bpm_integration.md` - BPM system guide  
+- [ ] Update `API_REFERENCE_PRO.md` with 5 new tools
+- [ ] Create troubleshooting guide for MIDI issues
+- [ ] Video/gif demos of Session View workflow
+
+---
+
+## Current Sprint Assignment
+
+**Sprint 8 (Active):** MIDI Instrument Loading + BPM Integration  
+**Owner:** Qwen + Kimi  
+**Goal:** MIDI tracks sound without manual intervention  
+**Deadline:** TBD (user decides priority)
+
+**Next:** Sprint 9 (Max for Live or Arrangement Recording)
