a feature wish for the FMOD SANDBOX.  
I wish I could use trigger zones to trigger events and distance options to test used parameters.

f.e.  
I am entering a circle zone = music starts  
The closer I get to the center of that circle the intensity parameter is changing.

I can see how it’d be useful to be able to add complex sequences and triggers to scenes in the sandbox! I’ll add this suggestion to our feature and improvement tracker.
