Retrieving the Sequence Division Type

The division type of a MIDI sequence determines the amount of time between MIDI events in the sequence. To determine the division type of a sequence, use the MCI_STATUS command and set the dwItem member of the MCI_STATUS_PARMS structure to MCI_SEQ_STATUS_DIVTYPE .

If the MCI_STATUS command is successful, the dwReturn member of the MCI_STATUS_PARMS structure will contain one of the following values to indicate the division type.

Value Division type
MCI_SEQ_DIV_PPQN PPQN (parts-per-quarter note)
MCI_SEQ_DIV_SMPTE_24 SMPTE, 24 fps (frames per second)
MCI_SEQ_DIV_SMPTE_25 SMPTE, 25 fps
MCI_SEQ_DIV_SMPTE_30 SMPTE, 30 fps
MCI_SEQ_DIV_SMPTE_30DROP SMPTE, 30 fps drop frame

You must know the division type of a sequence to change or query its tempo. You cannot change the division type of a sequence by using the MCI sequencer.
