If i remember correctly, FMOD Designer had the concept of **simple events** that would cost less CPU and/or memory. An event would be considered simple if there were no parameters and things like that. The details of the old system are not important here.

Is there such a concept in FMOD Studio? Where can I find documentation about it?

Thanks.

Simple events in FMOD Designer did not use less memory or cpu.  
The cpu and memory is dependant on the sounds loaded, and instrument voices that are played.

Simple events were based on a need for a shortcut to handle the ‘simple’ case of just wanting to play a wav without setting up a track or parameters, which is purely a UI thing.
