"type" will tell you which type of event it is (you use this to
interpret or cast the event data
"d" in your code below will be a pointer to the event data
"eventData" is the size (number of bytes) that "d" is pointing too
So, your print out is saying that your event data is 22 bytes long.

Thanks Bill!
type=kMusicEventType_MIDIChannelMessage;

Boolean hasCurrentEvent;
MusicEventIteratorHasCurrentEvent(iter, &hasCurrentEvent);
while (hasCurrentEvent) {
MusicEventIteratorGetEventInfo(iter,&timeOfEvent,&type,&d,&eventData);
printf("Current music event: %d\n",eventData);
MusicEventIteratorNextEvent (iter);
MusicEventIteratorHasCurrentEvent(iter, &hasCurrentEvent);
}
and got this output:
Current music event: 22
I'm pretty sure I'm doing some basic things incorrectly.
I was desperately trying to find any working examples and failed.
What is the data type of myEvent should be?
Also, could you, please, point me to a proper usage example of
MusicTrackNewExtendedControlEvent?
What I'm trying to do is to read individual events as they occur and
insert instrument and.or bank change events in certain positions.
Probably just use the MIDIControl events to set bank and patch change
events

Your help is greatly appreciated.
