A Bus is a named mix bucket with its own gain stage, optional FX inserts,
a voice-concurrency limit, and an optional sidechain key.

Voices are connected to bus.input. The master receives bus.output.

level/mute use 10ms ramps to avoid clicks; raw gain.value writes would
pop audibly on browsers that don't smooth the parameter. Public time

# Bus

A Bus is a named mix bucket with its own gain stage, optional FX inserts, a voice-concurrency limit, and an optional sidechain key. Voices are connected to bus.input. The master receives bus.output. level/mute use 10ms ramps to avoid clicks; raw gain.value writes would pop audibly on browsers that don't smooth the parameter. Public time arguments (fadeTo) are seconds.

## Members

-   constructor
-   fxInput Sub-bus the FX chain splices into: input → fxInput → (fx…) → output.
-   input
-   name
-   notifySoloChange Engine-injected callback fired when this bus's solo state changes. The Engine uses it to coordinate the global "any soloed → mute the rest" rule across every bus in the graph. Bus does not depend on Engine; the callback is the only escape hatch.
-   output Output node — connect to master.input or another bus.input for sends.
