Generate music or sound effects from a prompt plus tag pickers — moods, genres, instruments and tempo for music; sound types, environments and actions for SFX — with model-aware duration options.
Where: canvas → left rail → Add → Audio → Gen Music / SFX — Add a Music node and toggle Music or SFX mode
Key ideas
- Music vs SFX mode: The node has a Music/SFX toggle. Music uses Lyria models; SFX uses an effects model. The available tag groups and duration options change with the mode.
- Tag pickers: In Music mode, stack moods, genres, instruments and a tempo; in SFX mode, pick sound types, environments and actions. Selected tags are folded into the prompt sent to the model.
- Model-aware duration: Duration options depend on the model: Lyria 3 clip is a fixed 30s (no selector), Lyria 3 Pro offers 30–180s, and SFX uses short 1–30s options; an invalid duration is clamped on mode/model change.
- Prompt + advanced knobs: Type a free-text prompt (edited from the sidebar, auto-creating a Text node) and, on Lyria 3, set a negative prompt and seed.
- Gen Music / SFX card: MusicGenerationNode uses the generic shared-card path. Generate either music or a sound effect with model-specific prompt, duration, format, and creative controls.
