IDirectMusicPatternTrack8

The IDirectMusicPatternTrack8 interface represents a track that contains a single pattern. A pattern track is similar to a sequence track, but because it contains music values rather than fixed notes, it responds to chord changes.

You can obtain this interface by passing IID_DirectMusicPatternTrack to the IDirectMusicTrack8::QueryInterface method of the track.

The IDirectMusicPatternTrack8 interface has the following methods:

Creating a segment CreateSegment
Setting the pattern SetPatternByName
Setting the variation SetVariation

All COM interfaces inherit the IUnknown interface methods. This interface supports the following three methods:

IUnknown AddRef
  QueryInterface
  Release
