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
• Async generation
• Job polling
• Validation tools

---

8. Piano Used

NO - No piano assets or piano MIDI roles were used.

Harmonic support provided by:

• PAD (synth pad texture)
• CHORDS (synth chords)
• PLUCK (synth pluck)

All samples from user's Midilatino library (non-piano timbres).
