I have an old, nearly complete, GM8 game I may not be able to convert to Studio. I'd like two separate volumes for sounds and music. Is there an extension to do this in GM8? I've heard about Fmod Sound System and Supersound. Do either do this, and how would I use one with GM8, or at least learn how to? Which one is simpler to use? Is one, or both free to use? If the game were put on Steam could I use or call these dlls in it, or not?
