I have no idea how to just make sounds within FMOD, I need help creating patches and testing within FMOD, as I don’t have anything to make games. I make music for others.
FMOD Studio does not produce sound itself, it plays sound files you provide and modifies them in real time.
Take a look into the Music folder of the Examples project included in your installation (it will be in the Documents/FMOD Studio folder on Windows, or the examples folder in the installation folder on Mac). Be sure to read the event properties to get an idea of what is happening and how.
