---

## 6. Is The Song Usable?

**Honest Assessment:** PARTIALLY

### What Works:
- KICK, HAT CLOSED, PAD, ATMOS have clips in Arrangement
- BPM and Key match target (95 BPM, Am)
- Palette uses user library (Midilatino packs)
- Auto-play is running

### What's Missing:
- 10 tracks have no Arrangement clips (Session View only)
- No audio tracks materialized
- No lead layer
- Returns have no sends configured

### User Action Required:
To hear the full song:
1. Press **Tab** to switch to Session View
2. Launch clips manually from each track
3. OR wait for Session-to-Arrangement commit

## 7. MCP-First Used

**YES** - No Python or shell recovery was needed.

All operations used MCP tools directly:
- Preflight checks

## 8. Piano Used
