Detailed Description

An interface to allow an AudioProcessor to implement extended VST3-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::getVST3ClientExtensions() method.

Member Function Documentation

queryIEditController()

virtual int32_t VST3ClientExtensions::queryIEditController ( const Steinberg::TUID  , void **  obj  )

virtual

This function may be used by implementations of queryInterface() in the VST3's implementation of IEditController to return additional supported interfaces.

queryIAudioProcessor()

virtual int32_t VST3ClientExtensions::queryIAudioProcessor ( const Steinberg::TUID  , void **  obj  )

virtual

This function may be used by implementations of queryInterface() in the VST3's implementation of IAudioProcessor to return additional supported interfaces.

setIComponentHandler()

virtual void VST3ClientExtensions::setIComponentHandler ( Steinberg::FUnknown *  )

virtual

This may be called by the VST3 wrapper when the host sets an IComponentHandler for the plugin to use.

You should not make any assumptions about how and when this will be called - this function may not be called at all!

setIHostApplication()

virtual void VST3ClientExtensions::setIHostApplication ( Steinberg::FUnknown *  )

virtual

This may be called shortly after the AudioProcessor is constructed with the current IHostApplication.

You should not make any assumptions about how and when this will be called - this function may not be called at all!

getPluginHasMainInput()

virtual bool VST3ClientExtensions::getPluginHasMainInput ( ) const

virtual

This function will be called to check whether the first input bus should be designated as "kMain" or "kAux".

Return true if the first bus should be kMain, or false if the bus should be kAux.

All other input buses will always be designated kAux.

getCompatibleClasses()

virtual std::vector< String > VST3ClientExtensions::getCompatibleClasses ( ) const

virtual

This function should return the UIDs of any compatible VST2 plug-ins.

Each item in the vector should be a 32-character string consisting only of the characters 0-9 and A-F.

This information will be used to implement the IPluginCompatibility interface. Hosts can use this interface to determine whether this VST3 is capable of replacing a given VST2.
