I currently own a Roland XP80 expanded with Voice, Base & Strings, Drums and Session expansions. The problem is the display is fading out and the keyboard will eventually become useless and I can't find a replacement display anywhere, so I guess I'm stuck buying a new keyboard. Problem is, I wish to have one as close to or even better than the XP80, a workstation keyboard, and something that uses more advanced recording devices (USB, DVD ROM, ETC...) Any advice?
