this is how you download Sounds, Synthesizers and Demosongs and how to integrate them in to the MM. :) I hope this might help you!
follow these steps:
Download the Content on your PC via "Help" Button inside of the Programm and the Option "Download Soundpools"
After downloading, navigate with your PC to the downlaoded soundpackage and press doubleclick --> Soundpackage is now installing
Open the Music maker und click on the Button "Add Styles" which is on top of the Soundpool/Contentpool (where you choose the loops). ( Attention: in easymode this button is not visible)
Navigate to your musicmaker directory. Normally it is C>Programs>MAGIX>Music Maker. Choose the Folder "Basics" und press OK
Restart the program. All Sounds are now imported and from now on accessibleon every start of the MM
