## Detailed Description

Parameter Editing from host: Vst::IEditControllerHostEditing.

- [plug imp]
- [extends IEditController]
- [released: 3.5.0]
- [optional]

If this interface is implemented by the edit controller, and when performing edits from outside the plug-in (host / remote) of a not automatable and not read-only, and not hidden flagged parameter (kind of helper parameter), the host will start with a beginEditFromHost before calling setParamNormalized and end with an endEditFromHost. Here the sequence that the host will call:

# Example

//------------------------------------------------------------------------
plugEditController->beginEditFromHost (id);
plugEditController->setParamNormalized (id, value);
plugEditController->setParamNormalized (id, value + 0.1);
// ...
plugEditController->endEditFromHost (id);
