loops

Hello - It seems that Apple Loops utility is no more. At any rate, it no longer launches as of High Sierra upgrade. Is there any future for the Utility? If not, what are alternative methods for tagging meta-tags for Apple Loops? Thank you.

I've got lots of apple loops (audio loops) which I cannot use. Although they are in the same folder as the other ones, they are displayed in a dark way and I'm unable selecting them. Reindexing the loops does not change this behaviour. What's causing this and is there a way to solve this...
