Hi, I've got superior drummer 2.0 i'm running it with nuendo 3.0 my edrums is a Legacy DD506.Now im running a USB from my edrums to the computer and out to my mixer.I seem to to be getting a signal in nuendo but no responce from superior drummer,I've tried the learn button and a few other things but nothing.Can anyone help me out with this or does someone with the same edrums as mine had this problem?any feedback would be great..cheers
