## Detailed Description

Parameter Editing from Host.

- [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 flagged parameter (kind of helper parameter), the host will start with a beginEditFromHost before calling setParamNormalized and end with an endEditFromHost. Here the sequencing, the host will call:

- beginEditFromHost ()
- setParamNormalized ()
- setParamNormalized ()
- ...
- endEditFromHost ()
