DirectMusic Stream Data Range

This example uses a KSDATARANGE_MUSIC structure to describe the data range for a DirectMusic stream.

  DataRange.FormatSize  = sizeof(KSDATARANGE_MUSIC);
  DataRange.Flags       = 0;
  DataRange.SampleSize  = 0;
  DataRange.Reserved    = 0;
  DataRange.MajorFormat = STATICGUIDOF(KSDATAFORMAT_TYPE_MUSIC);
  DataRange.SubFormat   = STATICGUIDOF(KSDATAFORMAT_SUBTYPE_DIRECTMUSIC);
  DataRange.Specifier   = STATICGUIDOF(KSDATAFORMAT_SPECIFIER_NONE);
  Technology            = STATICGUIDOF(KSMUSIC_TECHNOLOGY_PORT);
  Channels              = 0;
  Notes                 = 0;
  ChannelMask           = 0xFFFF;
