Interface ChainProcessorState

false when bypassed.

Stable id (survives reorder; how a reorder/enable/plugin verb references it).

The processor role (trim / gate / eq / dynamics / insert / fader).

Human label (Trim/HPF, A, Fader, …).

The processor's controls in the GENERIC form (mixer-standard binding matrix, Control row) — present on the kinds with a bridged store (eq, gate). A client can render these with one ParamControl per entry and write back via chain.param.set; the typed frames (eq.state, gate.state) remain the live update channel.

The last-applied values on this processor's CURATED plugin (the optional mod-host chain plugin, not the built-in DSP), keyed by control-port symbol / lv2:Parameter URI — the console's echo of what the chain params / properties rows have been told. Present only on processors that host a plugin and have received a param set; lets other clients + late joiners converge their plugin panels from server truth.

Curated plugin URI hosted here (stages + inserts); absent for an empty slot / the fader.
