@jimmy-l Have you bought Magix Soundpools or loops with a different label?

Have you already extracted the ZIP-files? You can do this by right clicking on the ZIP-file.The option is in the context menu.

You can add Soundpool loops to the loop manager window in Music Maker by clicking on the small gear icon. Here you can add new directories with your loops.

But this will only work for Magix Soundpool loops. Loops from different label can be dragged and dropped from the internal file browser or from the Windows Explorer into your projects.
