A stream-like passage is a dense run of single-note starts. This example moves between columns at regular intervals.

Open the diagram to view the full-size image. These are original timelines, not screenshots of a real map. Column numbers are not keyboard bindings. The example is illustrative rather than a test of the entire-chart classifier.

The broad v1 analyzer measures closely spaced single-note events and run length. It does not require a fixed alternating-column pattern, so repeated-column passages can contribute too.

.stream

Use either form as an active player. The shared room’s future selections use the preference; already visible queue entries stay in place. Use .style or .map to inspect the current Mania chart and .pool for active filters.

The human description “stream” can be more specific than this heuristic. Rhythm, speed, length, and other structures still vary; this is not a stamina classification.

When strict fresh choices run out, style fallback can broaden the selection while keeping the active eligibility boundaries. Expanded spelling aliases are supported in the confirmed live v6.6.17 release.

See the visual pattern atlas, the command reference, practical style examples, and style selection.

The structural idea also applies in 7K. The room keeps its key mode; selecting Stream does not convert a 4K room into 7K or change the player’s bindings.
