Razer Synapse Surround Pro vs Razer App 7.1 Surround Sound

Hey, So I have Surround Pro that is bundled with Synapse , but there's a new seemingly different Razer App that has like a Standalone 7.1 Surround Sound. Are these any different? The Surround Pro is the paid version that I have. I downloaded 7.1 surround sound also because I just reformated my SSD and thought that that was the one I had . The 7.1 SS also says it requires an activation key to use, which I don't seem to have. Thanks for help and info
