I have a MOXF6 and have been playing it for a while, but I'm still kind of lost when it comes to some of the more complex functions. I want to be able to split the keyboard so that most of the lower keys control a sound (the Giant keyboard on Kontact 5 player) on my computer that is plugged into the keyboard via usb (that's called a VST right?), and the highest octave or two controls an internal sound, say one of the organ sounds. I think this has something to do with the Master mode and I tried to read Yamaha's article on Understanding the Master Mode, but it just confused me. How do I do this? And any other tips for using the master mode, or finding a place where it is explained in a simpler way than in that article?
