Thanks for replies. As I wrote, Groove Agent ONE is broken for me.
Ah drum maps. Never used them before either.
I guess what I was really asking for was a way to do what drum maps do, but inside Beat Designer, or if Beat Designer could get the names of the sounds automagically.
Drum mapping feels like a necessary evil just providing glue between Beat Designer and the VSTi being triggered (NI Battery 3 in this case).
So I basically have to create a drum map for every kit on the VSTi I want to trigger… 
But stingray mentions “if it knows it”… So there IS a way for Beat Designer to ask the target VSTi for the sounds?
Does this happen with Groove Agent ONE? If so, there’s no way to get it with NI Battery I assume
