I have the Event x midi'd to my SX900. I don't have the knowledge or patience to go through the hoops that you guys are. However, for my purposes, I have both fully active and bring in sounds of both or either with the sliders and master volumes. I am over the top on the Event X and what it brings to my Yamaha. I may not do this like the big boys, but I have a heck of a lot of fun bringing whatever I think is needed from either.
