That will not work for me. If I really need to use it like this, I would rather invest in sound module. Most of the features that makes Genesys the ultimate studio keyboard are already in sk880. So I do not need a second heavy keyboard. I need a lighter keyboard and a heavy duty one to replace Sk880. But to tell you honesty, SK880 is a wonderful keyboard. I will not even trade it even if I get Genesys88.
