How to access loops? did you install extra free contents? if so when Magix Music Maker 16 Premium is open turn off easy mode, look top left there MAGIX written under it there are two buttons click on right side. Now you will be able to see Soundpool, File Manager, Synthesizer etc, On the extreme left under Soundpool there are styles choose any then on right side from instruments such as Drum, Bass, Guitar click on it you will see the collection under Add styles. Choose from here and drag and drop on arranger.
