Detailed Description

An interface to allow an AudioProcessor to implement extended VST2-specific functionality.

To use this class, create an object that inherits from it, implement the methods, then return a pointer to the object in your AudioProcessor::getVST2ClientExtensions() method.

Member Function Documentation

handleVstPluginCanDo()

virtual pointer_sized_int VST2ClientExtensions::handleVstPluginCanDo ( int32 index, pointer_sized_int value, void * ptr, float opt )

virtual

This is called by the VST plug-in wrapper when it receives unhandled plug-in "can do" calls from the host.

handleVstManufacturerSpecific()

virtual pointer_sized_int VST2ClientExtensions::handleVstManufacturerSpecific ( int32 index, pointer_sized_int value, void * ptr, float opt )

pure virtual

This is called by the VST plug-in wrapper when it receives unhandled vendor specific calls from the host.

handleVstHostCallbackAvailable()

virtual void VST2ClientExtensions::handleVstHostCallbackAvailable ( std::function< VstHostCallbackType > && callback )

virtual

This is called once by the VST plug-in wrapper after its constructor.

You can use the supplied function to query the VST host.
