MIDI.SoundDurationGet method |
|
Remarks
Obtains the duration of the loaded MIDI stream.
This method keeps count of eventual tempo changes so the reported duration may vary depending upon the current tempo. If you should need retrieving the original duration of the loaded song you should use the SoundDurationGet method by setting the bKeepCountOfRateChange parameter to "BOOL_FALSE".
For further details about the use of MIDI protocol see the MIDI object section and the How to deal with MIDI protocol tutorial.
