SymphonyGen

Generates orchestral music by writing a harmony skeleton first, then orchestrating on top of it - so existing pieces can be re-orchestrated, not just composed from scratch. Uses a 3D hierarchical framework with cascading decoders over bar, track and event axes, RL refined against CLaMP 3 audio embeddings, and dissonance-averse sampling. Beats SymphonyNet and NotaGen-X.
