First, I see you chose Music Maker as your product but then asked about "Magix Pro". There is no such product as Magix Pro so first, please confirm exactly which Magix product you have, including its exact variant and build number (you can check under Help>About).
Then, please read this post and give us ALL the details requested there.
Then, you need to tell us exactly what focusrite studio equipment you have and what you want to be able to use it for.
Sorry for all the questions but, without all that additional information from you, we are likely to be using a lot of guesswork!
