Studio One comes with a collection of audio loops and software instruments. The files associated with this are organized into so-called Sound Sets. How many Sound Sets you get depends on the version of Studio One you have.
By default, the Sound Sets are stored on the system drive but at some point, for some reason, you might want to move these files to another location on your computer or to an external location.
This video is about how to move the sound sets and also about some things you should take into consideration before doing so.
