The DirectMusicPerformance.SendMIDIPMSG method sends a performance message containing information about a MIDI channel message not covered by other methods.
object.SendMIDIPMSG(lTime As Long, _ flags As Long, _ channel As Long, _ status As Byte, _ byte1 As Byte, _ byte2 As Byte)
If the method fails, it raises an error, and Err.Number can be set to one of the following values:
DMUS_E_NO_MASTER_CLOCK |
DMUS_E_ALREADY_SENT |
DMUS_E_INVALIDARG |
If the time of the message is set to 0 and the flags parameter contains DMUS_PMSGF_REFTIME, it is assumed that this message is cued to go out immediately.
Because the channel is specified in another parameter, status does not contain the channel number in the 4 lower bits, as it would in a standard MIDI message. Thus status is &H80 for a note-off, &H90 for a note-on, and so on. See the MIDI specification for other status bytes.
