The Signal Layer Between Music and Light

Let one musical state reach the room

The music player knows what is playing. The video system and the lights need that knowledge too, in different forms. MixMan Coordinator sits between them: it receives playback data, normalizes it, and translates it for each visual consumer.

Normalize before distributing

Its primary source can be MixMan's public current-playback projection, polled at a configurable interval. It can also accept external now-playing updates through the same normalized pipeline, allowing a side-stream source to keep visual systems active when MixMan is unavailable or intentionally not configured. Both paths produce a consistent internal representation of track identity, playback state, timing, color, intensity, and available metadata.

One input, two visual destinations

Each destination receives its own representation of the same normalized musical state.

Keep partial failure survivable

Each downstream receives a purpose-built payload. Visualizer Stream gets the track and recommendation context it needs to construct a video presentation, while DungeonOPC receives the compact now-playing state used to guide a physical lighting environment. Raw upstream responses are not forwarded wholesale, reducing coupling and preventing one consumer from becoming dependent on unrelated source details.

The coordinator is designed to remain useful during partial outages. Its process health does not fail merely because a dependency is unreachable, and disabled services are represented explicitly. Status, current state, diagnostics, traffic summaries, and delivery counters give an operator enough information to distinguish a healthy coordinator from a healthy source or a successful downstream delivery.
