The generator will sleep between each message by default. Messages are yielded with correct timing. The time attribute is set to the number of seconds slept since the previous message. By default you will only get normal MIDI messages. Pass meta_messages=True if you also want meta messages. You will receive copies of the original messages, so you can safely modify them without ruining the tracks. By default the system clock is used for the timing of yielded MIDI events. To use a different clock (e.g. to synchronize to an audio stream), pass now=time_fn where time_fn is a zero argument function that yields the current time in seconds. gN)rYsleeprr)r' meta_messagesnow start_time input_timery playback_timeduration_to_next_events rplay MidiFile.playsj&U  C (( "JEJ.M%/%?
