Don't the Superior kits all come with drum maps? There are also some GM maps for various Superior kits in the Groove Monkee Midi packs. However, because most of these maps contain all the i-mappings as well, they are rather large and cumbersome. Because of this, I've had to make my own. It's time consuming but not that difficult. I always end up moving the kit pieces around so as too keep them together. It's much easier to edit a midi track that way.
I'll try and dig up what I have.
