# VST3 interfaces
See
[docs/vst3.md](https://github.com/robbert-vdh/yabridge/blob/master/docs/vst3.md)
for more information on how the serialization works.
The following interfaces are not yet implemented:
- Every interface introduced after VST 3.0.0
- The [Presonus extensions](https://presonussoftware.com/en_US/developer),
although most of these things seem to overlap with newer VST3 interfaces
VST3 plugin interfaces are implemented as follows:
| yabridge class | Included in | Interfaces |
| -------------------------- | ------------------- | ------------------------------------------------------ |
| `YaPluginFactory` | | `IPluginFactory`, `IPluginFactory2`, `IPluginFactory3` |
| `Vst3ConnectionPointProxy` | | `IConnectionPoint` through `YaConnectionPoint` |
| `Vst3PlugViewProxy` | | All of the below: |
| `YaPlugView` | `Vst3PlugViewProxy` | `IPlugView` |
| `Vst3PluginProxy` | | All of the below: |
| `YaAudioProcessor` | `Vst3PluginProxy` | `IAudioProcessor` |
| `YaComponent` | `Vst3PluginProxy` | `IComponent` |
| `YaConnectionPoint` | `Vst3PluginProxy` | `IConnectionPoint` |
| `YaEditController` | `Vst3PluginProxy` | `IEditController` |
| `YaEditController2` | `Vst3PluginProxy` | `IEditController2` |
| `YaPluginBase` | `Vst3PluginProxy` | `IPluginBase` |
| `YaProgramListData` | `Vst3PluginProxy` | `IProgramListData` |
| `YaUnitData` | `Vst3PluginProxy` | `IUnitData` |
| `YaUnitInfo` | `Vst3PluginProxy` | `IUnitInfo` |
VST3 host interfaces are implemented as follows:
| yabridge class | Included in | Interfaces |
| --------------------------- | --------------------------- | ------------------- |
| `Vst3HostContextProxy` | | All of the below: |
| `YaHostApplication` | `Vst3HostContextProxy` | `IHostApplication` |
| `Vst3ComponentHandlerProxy` | | All of the below: |
| `YaComponentHandler` | `Vst3ComponentHandlerProxy` | `IComponentHandler` |
| `YaUnitHandler` | `Vst3ComponentHandlerProxy` | `IUnitHandler` |
| `Vst3PlugFrameProxy` | | All of the below: |
| `YaPlugFrame` | `Vst3PlugFrameProxy` | `IPlugFrame` |
The following host interfaces are passed as function arguments and are thus also
implemented for serialization purposes:
| yabridge class | Interfaces | Notes |
| -------------------- | ------------------- | ---------------------------------------------------------------------- |
| `YaAttributeList` | `IAttributeList` | |
| `YaEventList` | `IEventList` | Comes with a lot of serialization wrappers around the related structs. |
| `YaMessage` | `IMessage` | |
| `YaMessagePtr` | `IMessage` | Should be used in inter process communication to exchange messages |
| `YaParameterChanges` | `IParameterChanges` | |
| `YaParamValueQueue` | `IParamValueQueue` | |
| `VectorStream` | `IBStream` | Used for serializing data streams. |
And finally `YaProcessData` uses the above along with `YaAudioBusBuffers` to
wrap around `ProcessData`.
