You can also create fade-in behavior within the FMOD event itself. That way you don’t even need to worry about doing it in BluePrints.

If you have an active music event playing at all times and you want to lower it at a certain location? There are a few ways to go about this, it depends on what your end goal is.

WHat you may want to do is, assign the music event to a Bus Channel in FMOD the use the ButSetFaderLevel node in UE4 to drive the volume of the channel. You can use a volume trigger to send the overlap event

As JB has said, there are a few ways to go about this.  
Another way could be using parameters and automation inside studio to control volume levels that can then be set via triggers for example.

Thx guys.  
Parametr, triger box and volume automation works fine besides i found “smoothing”, when You click on paramter twice. Now I can fade out my music for 5 seconds
