Remarks
The GUID for the format type is NULL, but the format block contains the following structure:
typedef struct _MIDIFORMAT {
DWORD dwDivision;
DWORD dwReserved[7];
} MIDIFORMAT, FAR * LPMIDIFORMAT;
The dwDivision member specifies the time division of the file. The time division is given in the header of any standard MIDI file (SMF), in the MThd chunk. The MIDI Renderer sets this property on the MIDI data stream by calling the midiStreamProperty function.
Samples from the MIDI Parser filter contain one second of MIDI data. The MIDI Renderer uses the midiStreamOut function to render the MIDI data. Each sample is a
