No, they're just an extra from Cake. Jimmy Landry programmed them as starting point for making your own sounds.
They're very good.
Cake seem to be giving away lots of little bits at the moment in addition to the Content Club.
I'm always grateful for the free things, even if they are not immediately useful to me. I don't use loops, but did not complain when they gave us the free ones. In fact, having listened to
Shan@trustmedia.tv's track Oyster, where he did some great things with loops, I may dig them out and have a play..
Next Content Club gift is due for March - April. It's bi-monthly.
