Default Audiopath
The default audiopath is the one used when a segment is played by using IDirectMusicPerformance8::PlaySegment, or when no audiopath is specified in a call to IDirectMusicPerformance8::PlaySegmentEx.
You can create an audiopath and make it the default by specifying a standard type in the dwDefaultPathType parameter of IDirectMusicPerformance8::InitAudio.
Any existing audiopath can be made the default audiopath by passing it to IDirectMusicPerformance8::SetDefaultAudioPath. Retrieve the default audiopath by using IDirectMusicPerformance8::GetDefaultAudioPath.
