Determines the total playing time of a midi, in seconds.
This function will simulate playing the given MIDI, from start to end, to
determine how long it takes to play. After calling this function, midi_pos
will contain the negative number of beats, and midi_time the length of the
midi, in seconds.
Note that any currently playing midi is stopped when you call this function.
Usually you would call it before play_midi, to get the length of the midi to
be played, like in this example:
length = get_midi_length(my_midi);
pos = midi_time;
textprintf_ex(screen, font, 0, 0, c, -1, "%d:%02d / %d:%02d\n",
pos / 60, pos % 60, length / 60, length % 60);
} while(pos <= length);
Returns the value of midi_time, the length of the midi.
