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
