Hi, I’ve created an Event Instance and started, but when I try to trigger the sustain point by EventInstance.triggerCue(); like specified in the documentation I get this error in Unity  
‘EventInstance’ does not contain a definition for ‘triggerCue’ and no accessible extension method ‘triggerCue’ accepting a first argument of type ‘EventInstance’ could be found (are you missing a using directive or an assembly reference?)  
What am I doing wrong?

Hi,

Could I get a link to the documentation you reference? I believe you are looking for [EventInstance::keyOff()](https://fmod.com/docs/2.02/api/studio-api-eventinstance.html#studio_eventinstance_keyoff).

Hope this helps!
