Live
Auto
Timed sequences. Building steps, setting their durations, and what happens when a sequence reaches its end.
Auto is a playlist of fills that runs itself. Each step is a solid colour, a gradient or a random fill and carries its own duration, up to ninety-six steps, which is roughly one song.
The player sits on top: one bar for the whole playlist, each step sized by its share of the total and painted with its own preview, with an indicator riding across as it advances. Below that, play, pause, stop, an elapsed and total clock, and the loop toggle.

Playback running: the indicator crossing the timeline while the preview changes with it.
The grid underneath is where you build. Steps reorder by dragging, and the other tiles shift live into the arrangement they would take if you dropped now. Tapping a step jumps the playhead to it.
A random step is worth understanding: each phone picks its own colour once when the step is broadcast and holds it for the whole duration rather than shuffling. That is what makes it read as a scattered crowd instead of noise.
Leaving the mode mid-playback sends a stop, so nobody is left holding a frozen colour.
