Yea so far I have only been able to get Playoneshot to work. I am pretty sure the play node you are using comes from the FMOD Event emitter script which is a script that is used to play events. It is like a pre-made fmod script for you. So I don’t think it’s possible to use that to play an event.
You need to be able to make an EventInstance variable how you can with a C# script but that exists within the FMOD.STUDIO namespace, which isn’t exposed to FMOD.
So yea I think for full functionality we gonna need to wait for an official release from FMOD.
