Embedded cockpit: VST3 parameters, editor and renders through theDAW, .gan plugins from theDAW, host file pick
… and plays it live A track's effect chain takes a second family of entries, kind host:<id>, beside the cockpit's own fourteen. When theDAW frames the cockpit it lists 'rack-fx' in sway/host-ready and puts its effect API on this window (window.theDAWHost: catalog, prepare, build). The cockpit adopts it, registers the catalog as kinds, and the transport builds each entry with theDAW's own effect code on the cockpit's AudioContext, in the track's chain where its own effects sit. The parameters draw with the track panel's sliders and picks, and bind to pads, knobs, gestures and sections like any other. The entry (kind, values, on / off, name) is saved in the project. With no host it stays in the project, passes audio through, and the list says it needs theDAW. A cockpit older than this kind drops the entry on load. scripts/test-hostfx.js covers the project round trip and the kind registry.
…synth get effect chains A host with the 'vst-live' cap runs each VST3 row of a track's chain in its own plugin host as the track plays. Each row has a stable id, which names the running plugin across every rebuild; its rawState plus stateHost is the one state a live plugin, a render and the plugin's window read and write, and the host hands every state it captures back to the row. The clips feed the plugins in order as the wet branch; the dry branch waits as long as the chain's reported latency, every track waits for the slowest chain, and the transport (play, stop, seek, loop seam, tempo) reaches every plugin. LIVE on the track's VST3 header switches back to rendered files. The kit and the synth play through two buses (timeline.buses): each has its own effect chain and a live VST3 chain, opened from EFFECTS in the KIT and SYNTH drawers or from the empty panel. The Miracle Mile template carries the song on its audio track.
