The Roland AT350C had all the same sounds and features as the rest of the Atelier line, however it was a pig to play on the fly due to limited real estate for the controls, (You got to everything through menus) thus you really needed to program everything beforehand, (This is the same problem arrangers have) whereas with a normal organ like the SKX you can play any request people make (Assuming you know it) without needing to set everything up first.
