Thanks Mr. Bomabastic and Bernie, but I just may be dreaming. There are several programs that will edit files for the SD1Plus from GM, but nothing else involving midi files. I've been using the Midjay Plus (and the Midjay before that) since their respective releases so I've accumulated and edited lots of files. I have a custom SD1Plus that I want to put back in action. I do use the 2 pieces together frequently, registrations on the SD1+ and midi files with the Midjay Plus ... Oh well, may have to continue doing that.
