Before you go running around changing things, I have Jamstix and have never seen that problem. All the kits I use are already mapped to the GM standard or at least they seem to be. It's possible there's some that are wrong and I've not noticed it. Check out everything else first and visit the Rayzoon forum. In case you're not aware of this already, JS will work fine as a drum sound module in Real Band but unfortunately, you can't use it's "brain" function to create it's own drum track. It's a well known problem with the VST implementation in RB.
