I’m glad to hear you were able to get it working.

The various causes of latency are covered in more detail in [this thread](https://qa.fmod.com/t/transitions-latency-when-changing-parameter/14383/35), but the short version is that there are some circumstances where it is physically impossible to avoid latency, and changing the value of a parameter in order to change the behavior of an event involves the intersection of multiple such circumstances.
