Detailed Description
Extended plug-in interface IEditController for note expression event support: Vst::INoteExpressionController.
- [plug imp]
- [extends IEditController]
- [released: 3.5.0]
- [optional]
With this plug-in interface, the host can retrieve all necessary note expression information supported by the plug-in. Note expression information (NoteExpressionTypeInfo) are specific for given channel and event bus.
Note that there is only one NoteExpressionTypeID per given channel of an event bus.
The method getNoteExpressionStringByValue allows conversion from a normalized value to a string representation and the getNoteExpressionValueByString method from a string to a normalized value.
When the note expression state changes (for example when switching presets) the plug-in needs to inform the host about it via IComponentHandler::restartComponent (kNoteExpressionChanged).
