[3.6.5] Prefetchable

On this page:


Indicates if the plug-in supports prefetch (dynamically): Vst::IPrefetchableSupport.

  • [plug imp]
  • [extends IComponent]
  • [released: 3.6.5]
  • [optional]

The plug-in should implement this interface if it needs to dynamically change between prefetchable or not. By default (without implementing this interface), the host decides in which mode the plug-in is processed. For more info about the prefetch processing mode check the ProcessModes::kPrefetch documentation


tresult PLUGIN_API myPlug::getPrefetchableSupport (PrefetchableSupport& prefetchable)
    prefetchable = kIsNeverPrefetchable;
    switch (myPrefetchableMode)
        case 0: prefetchable = kIsNeverPrefetchable; break;
        case 1: prefetchable = kIsYetPrefetchable; break;
        case 2: prefetchable = kIsNotYetPrefetchable; break;
    return kResultOk;
