DirectMusicPerformance

An object of the DirectMusicPerformance class is the overall manager of music playback. It maps performance channels to a port, plays segments, dispatches messages, requests and receives event notifications, and sets and retrieves music parameters. It also has several methods for getting information about timing and for converting time and music values from one system to another.

If an application wants to have two or more complete sets of music playing at the same time, it can do so by creating more than one performance object. Separate performances obey separate tempo maps and play completely asynchronously, whereas all segments within one performance play in lock step.

The DirectMusicPerformance object is obtained by using the DirectX7.DirectMusicPerformanceCreate method.

The methods of the DirectMusicPerformance class can be organized into the following groups:
