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.
