Timing and State

triode exposes frame timing and mutable live state through triode.synth.

Time and frame hooks

• time: seconds-like runtime clock advanced during tick.
• update(dt): per-frame user callback.
• afterUpdate(dt): post-render callback.
• onFrame((dt, time) => {}): helper that sets update with direct time access.

Inputs and interaction

Input hooks are part of synth state:

• click, mousedown, mouseup, mousemove
• keydown, keyup

These are useful for parameter nudging and interaction-driven sketches.

Global and non-global state

• makeGlobal: true: installs helpers on global scope.
• makeGlobal: false: keeps API under triode.synth.
• liveGlobals(enable?): toggles this behavior at runtime.

For embedded apps and multi-instance reliability, prefer non-global mode.

Stateful render behavior

Accumulation behavior is controlled by clear settings:

• Output level: o0.clear(...) / o0.autoClear(...)
• Scene/chain level: stage().clear(...), osc(...).clear(...)

amount < 1 keeps trails/fade accumulation; amount >= 1 behaves as full clear.
