====== Chordjack patterns ======

A chord is a group of notes with the same start time. Closely spaced chord events create chordjack-like structure. Some pairs in this diagram repeat, and later pairs move to other columns.

===== Read the example =====
{{:images:patterns:chordjack_4k.png?640|Closely spaced two-note chords; pairs can change columns. Earliest events are at the top; time increases downward.}}

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.

===== What the analyzer measures =====
The analyzer looks for consecutive multi-key events close together, the share of chord events, and chordjack runs. It does not require every chord to use identical columns.

===== Choose this preference =====
<code>
.style chordjack
.chordjack
</code>
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.

===== Limitations =====
A single isolated chord is not a repeated chord sequence. A chart can also contain single-note streams, jacks, or long notes; style scores are not exclusive categories.

When strict fresh choices run out, [[wiki:style_fallback|style fallback]] can broaden the selection while keeping the active eligibility boundaries. [[updates:v6_6_17|Expanded spelling aliases]] are supported in the confirmed live v6.6.17 release.
