# Find a Setting

> Every setting, where it lives in the builder, and whether you can change it from the guided overview

Looking for one setting and not sure where it moved? Find it here, or type its name into
**Search all settings** in the assistant sidebar, which jumps straight to the field.

**Simple** marks the settings you can also change from the guided overview. Everything else needs
the full builder — switch with the **Simple / Advanced** control at the top of the assistant.

<Tip>
  Two cards open with presets rather than sliders: **Synthesizer settings** has Natural, Crisp & fast
  and Warm & slow, and **Turn taking** has Patient, Balanced and Snappy. Try a preset before moving
  anything by hand.
