Just load Real Guitar http://www.musiclab.com/products/realgtr_info.htm into your keyboard/module, and you can then use it in styles and/or on the keyboard.
It will also make both the onboard Korg Guitar mode, and the Roland Guitar mode sound pretty basic. (I doubt you would bother using them anymore)
Enjoy life, Play music
