Flowy: sound design (layered audio)

A soundtrack is built from SEPARATE layers, not one clip: a music bed under the whole piece, plus spot SFX/ambience tied to specific moments. Generate each layer as its own clip and mix them as audio tracks in the composition.

• generate_audio — prompt, mode: "sfx" | "music", duration_seconds (1–60, default 5). Poll get_generation.
• create_node — type: "audio" on a canvas project; same modes, duration_seconds up to 240 (use this for beds longer than 60s). Poll get_node.
