Hi. I found that there is a lack of “percussive” category on the new “music/kits/packs page” category list. I have contacted support already but maybe publishing it here will speed up fixing this simple and obvious bug.
Thanks for reporting! The percussion category was added to that page yesterday; you should be able to see it now. Let me know if not!
A-W-E-S-O-M-E. Thanks for fixing this so fast!
