DirectMusic File Structures

This section contains reference information for data structures used in DirectMusic files. Most applications do not need to know about these structures because each standard DirectMusic object handles the loading of its own data through its IPersistStream interface. The structures are chiefly of interest for music-authoring applications that need to save data in a format compatible with DirectMusic.

The following structures are used in DirectMusic files:
