Module audio 

The scene’s music: the synthesizer’s voice, and the sequences played into it.

The audio world is a world of its own, so the scene reaches it through jobs. Installing the voice is one question: it builds the voice and answers the entity that carries it, and every note the gameplay world plays is addressed to that entity afterwards. The sequences themselves live in the gameplay world, with the clocks that advance them, so a track’s play state is a component field rather than a job.
