Lets say i manage to create a single shot event that chains up with a separate event for a tail Sound and this constellation sounds as accurate as my looping event. So far so good. But how do the two approaches compare in terms of performance? As far as i understand it for the looping approach i would need to instantiate only one fmod event for each full auto action, no matter How high the RPM count goes. For your approach wouldnt i need to create one instance for… --- _[View the full topic](https://qa.fmod.com/t/fast-firing-weapon-problems/17287)._
