I'm trying to have a "safe list" of virtual instruments, synths, samplers and anything in between, that can be used for sfx production (mainly for videogame production) but it's often hard to understand what the license permits and what not. I also tried to contact some companies, but they didn't answer (so far) or sounded a bit elusive. Do you know of virtual instruments "safe" for that use? Is an absence of specific indication on the EULA to be assumed as an allowance or not?
EDIT Maybe I can clarify better: I'm talking of the so-called "synchronized use" - so NOT sfx creation for re-sale or re-licensing as a product
