What problem does it solve? It turns musical requests into reproducible songs by orchestrating YuE2 generation, SheetSage2 audio transcription, and ABC score editing, while preserving plans, invariants, and audible comparisons. ## Core Features & Use Cases - Song Generation: Generate songs with YuE2 in full, melody, or off chain-of-thought modes, retaining symbolic plans, tokens, and latents. - Audio-to-Score Covers: Transcribe recordings with SheetSage2 into ABC notation, strip chords, and re-render them as covers in new styles. - Score Editing & Reharmonization: Edit ABC scores with invariant checks, delegate bounded edits to agents, and regenerate audio from revised scores. - Use Case: Transcribe a reference recording to ABC, adapt the lyrics for singing, reharmonize the score as modern jazz, and deliver a local HTML listening comparison of before and after versions. ## Quick Start Use the yue2-music skill to generate a song from the example prompt in assets/prompt.json and save all plan artifacts.
