问题
I need to be able to have more freedom than just 2 octaves to create the thing I want to, but I can't with XNA. I do realize there probably isn't a way to get the program to accept a larger/smaller value, but is there a way around it? like taking the sound at the lowest pitch, and creating a new one as that so I can lower it more?
