IDirectMusicDownloadedInstrument

The IDirectMusicDownloadedInstrument interface is used to identify an instrument that has been downloaded to the synthesizer by using the IDirectMusicPort::DownloadInstrument or the IDirectMusicPerformance::DownloadInstrument method. The interface is then used to unload the instrument through a call to IDirectMusicPort::UnloadInstrument. Once the instrument has been unloaded, the interface pointer must be released by the application.

For an example, see Working with Instruments.

The IDirectMusicDownloadedInstrument interface has no methods of its own. Like all COM interfaces, it inherits the IUnknown interface methods. This interface supports the following three methods:

IUnknown AddRef
  QueryInterface
Release
