Hello! I created this event. Every time it loops ,one of the audios in each Multi Instrument should play one time to the end. And it works perfectly.  
But when I want to do another event like this, the Multi Instrument only plays a random audio once, then stops. Even if I copy an Instrument from that perfect event, still doesn’t loop! It only loops when I cancel the Async. But that way the audios won’t play in the way that one audio plays before another ends.  
Is this a bug? Or I missed something?  
The version is 2.02.04.

I solved it by myself. It turns out the head of the instrument can’t be located as same as the begining of the loop region. I don’t know why but it works. Thanks anyway! 💖
