Good Morning Folks,

- I’m making a heartbeat/tinitus sound for player health in my FPS game, whereby based on the health, the heartbeat tempo/tinitus volume increases.

- I’ve also created a health parameter, whereby any of the other sounds a player hears will be occluded (hi/lo filters etc.) and copy-pasted the event to each gameplay event (VO’s/monster roars/MUS/ pickups, reloads etc.)

If you are using FMOD Studio 2.00 then you can make your health parameter a global parameter. This way you can manipulate one parameter to affect all event instances and buses that use that parameter.

If you are using an older version of FMOD Studio, then you will need to use game code to manipulate the parameter on each event instance that uses this parameter.
