i’m trying to load vst plugin using low level api,and i’ve been able to get it’s name and type correctly,but the sound has no effects.when i load this plugin into audition and apply it into a track it works just fine ,the sound get effects immediately without any further settings.what did i do wrong?here is my code and any help will be appreciate.

```
//vst plugin
unsigned int baseHandle;
ERRCHECK(system->setPluginPath("G:\\vts\\en\\"));
//ERRCHECK(system->loadPlugin("ElastiquePitchV2O.dll", &baseHandle));
//ERRCHECK(system->loadPlugin("AutoTune5.dll", &baseHandle));
ERRCHECK(system->loadPlugin("SonitusFXEqualizerVST.dll", &baseHandle));
int countNested=0;
vector<FMOD_PLUGINTYPE> vtPluginTypes;
ERRCHECK(system->getNumNestedPlugins(baseHandle, &countNested));
for (int index = 0; index < countNested; ++index)
{
	unsigned int handle;
	ERRCHECK(system->getNestedPlugin(baseHandle, index, &handle));
	FMOD_PLUGINTYPE type;
	ERRCHECK(system->getPluginInfo(handle, &type, 0, 0, 0));
	vtPluginTypes.push_back(type);
}
FMOD::DSP *vstDsp=NULL;
result = system->createDSPByType(FMOD_DSP_TYPE_VSTPLUGIN, &vstDsp);
/*
    Add them to the master channel group. Each time an effect is added (to position 0) it pushes the others down the list.
*/
result = mastergroup->addDSP(0, vstDsp);
ERRCHECK(result);

```

It looks like you will want to use [System::createDSPByPlugin](https://fmod.com/resources/documentation-api?version=2.0&page=core-api-system.html#system_createdspbyplugin) rather than createDSPByType, so that the plugin is used to create the DSP.

The DSP created by using the VST type is just a shell DSP that you cannot really do anything with, you need to use the plugin to create the DSP.
