/** Default implementation for a non-distributable Plug-in that combines
|
|
processor and edit controller in one component.
|
|
\ingroup vstClasses
|
|
- [released: 3.0.2]
|
|
|
|
This can be used as base class for a VST 3 effect implementation in case that the standard way of
|
|
defining two separate components would cause too many implementation difficulties:
|
|
- Cubase 4.2 is the first host that supports combined VST 3 Plug-ins
|
|
- <b> Use this class only after giving the standard way of defining two components
|
|
serious considerations! </b>
