Yeah. And if I'm not sure yet I can ask the ppl of FMOD anyways when I request to get all the old versions and headers for inclusion. If they say yes, I'm quite secure for including it. Although I could it include it as Omorphia is Open Source and I don't have to care about the licencing as it's the developer using my Omorphia that includes FMOD in its distribution. I only plan to provide the interface.
