I am getting a window in cubase saying missing ports( see pics) . I need help configuring. Am very confused aobut port set up. I have follwed the Motif instructions and have it setup for FW with cubase. Motif is recognized by cubase. I can see signal in cubase when motif keyboard is played. I need a good explanation of port setup and/or a place to get really good info on this topic. It seems many people new to motif and daw have this issue. Appreciate the help. Thanks,DVF
