Import Sounds into the creator?

Hello, i’m surely not a genius with softwares (even for a zombie !) and, i cannot find how to upload some of my own sounds into the creator tool. Is there any button i miss somewhere ? Can you only acces to the officials Syrinscape sounds ? Please help a poor boy… and don’t stay too close cause i’m starving of human flesh :wink:

For those who have the same question, i’ve finaly been helped by a great guy who explain me that i need to make a copy from an original Mood to acces to the different uploading options !
