Was looking through the defualt 172 and right at the moment I found nothing in the beta about how to hook FMOD into XP I am hoping documentation is being written?
If not I would be willing to try and get some out, all I need to do is talk to the person from laminar who did the fmod coding. I think FMOD will really change the sound space that this sim is in. It would be handy to have an SDK on the developer x-plane website or somewhere in the install.
