Detailed Description

All parameter changes of a processing block: Vst::IParameterChanges

• [host imp]
• [released: 3.0.0]
• [mandatory]

This interface is used to transmit any changes to be applied to parameters in the current processing block. A change can be caused by GUI interaction as well as automation. They are transmitted as a list of queues (IParamValueQueue) containing only queues for parameters that actually did change. See IParamValueQueue, ProcessData

getParameterCount()

virtual int32 PLUGIN_API Steinberg::Vst::IParameterChanges::getParameterCount ( )

pure virtual

Returns count of Parameter changes in the list.

getParameterData()

virtual IParamValueQueue *PLUGIN_API Steinberg::Vst::IParameterChanges::getParameterData ( int32 index )

pure virtual

Returns the queue at a given index.
