Hi there!

On some hardware (2 people got the issue in a team of 30) setting a scatterer instrument to tempo causes a deadlock in FMod.  
After the event with the faulty instrument is played no more sounds could be heard and there’s an infinite wait when shutting down the FMod library.

This was noticed with FMod 2.02.16 and 2.02.22
