The
MIM_LONGDATA message is sent to a MIDI input callback function when a
system-exclusive buffer has been filled with data and is being returned to the
application.

dwParam1 = (DWORD) lpMidiHdr
dwParam2 = dwTimestamp
Parameters
lpMidiHdr
Address of a MIDIHDR structure identifying the
input buffer.
dwTimestamp
Time that the
data was received by the input device driver. The time stamp is specified in
milliseconds, beginning at zero when the midiInStart function was called.
