You can only set parameter values through the application running FMOD. You would need to create an external script that sends commands to the application running FMOD when it receives these inputs from the room.
It is hard to recommend a better way as we’re not sure what your current setup is like.
It would likely be easier to just have the external inputs talk directly to the application running FMOD.
ah you mean by using the scripting api?
You can do it like this as far as I know (example):
var event = studio.project.lookup("event:/Music/Level 03"); // get your ManagedObject:Event
var parameters = event.getParameterPresets(); // get an array of ManagedObject:GameParameter's
event.setCursorPosition(parameters, 1.0); // set the value of the GameParameter, could also be a Timeline
