Researchers have developed a hierarchical self-supervised world model for symbolic music, utilizing a 2.55M-parameter Swin V2 encoder trained on MIDI piano-roll images. This model, trained without labels or music-theory vocabulary, demonstrates that musical properties become decodable at different hierarchical levels corresponding to their time scales. The model can generate musical content with high fidelity and supports interactive prompting for masked inpainting, running efficiently on CPUs and Apple MPS hardware. AI
