Is there a way to change the attenuation falloff curve from code?
Alternatively, is there a way to globally control/default this setting? I don’t want to have to manually set every event’s falloff curve manually (I’ll forget about this and miss some).
I found a reference somewhere but the code was very old and I can’t find a way to reference the master track from an event instance in the current version.

Are you familiar with shared effects? As the name suggests, a shared effect is an effect that’s shared by multiple different events, and uses the same settings in each of those events.
To create a shared spatializer effect, select “Window \> Shared Effects Browser” to open the shared effects browser. Then, right-click i nthe new browser to open the context menu, and select “New Shared Effect \> New Effect \> FMOD Spatializer.” Give the new shared effect a name you’ll remember, and set its settings appropriately. Then, all you’ll have to do is add the shared effect to your events instead of the non-shared spatializer effect.
