IDirectMusicSegment8 Interface
The IDirectMusicSegment8 interface represents a segment, which is a playable unit of data made up of multiple tracks.
The segment object also supports the IDirectMusicObject8 and IPersistStream interfaces for loading its data.
IDirectMusicSegment8 supersedes the IDirectMusicSegment interface and introduces new methods.
In addition to the methods inherited from IUnknown, the IDirectMusicSegment8 interface exposes the following methods, arranged by category.
