Instance Property


The block that hosts use to schedule parameters.


var scheduleParameterBlock: AUScheduleParameterBlock { get }


As with the render block, a host should fetch this block before beginning to render, if it intends to schedule parameters.

The block is safe to call from any thread context, including realtime audio render threads. Subclasses should not override this; it is implemented in the base class and will schedule the events to be provided to the internalRenderBlock implementation

This version 3 property is bridged to the version 2 AudioUnitScheduleParameters(_:_:_:) API.
