Hi Lars, as you may have noted I gave up for a few months 
I don’t have any external resources but for what came with the software included when I bought the UR22mkII. I try to load what I call “automatic drum kit” (see my original posting) from the resources in the Cubasis LE 2.6 (or, using my Mac, in the Cubase AI 9.5 and it is the same thing there). I see a lot of different things in the Media Bay and can’t even really tell from the names in the result list what is just individual pieces of percussive sounds and what is “full automatic drum kits”? But anyway I can’t load them properly, when I try to drag them the project window the name appears in the drum track but the actual track is empty and there is no sound when you hit play.
