From 2 years experience and playing over 50x per month, I can assure you the Korg PA800 sounds THE SAME live, as in the demos. The editing tools are terrific and easy and you can customize your sounds in a snap. I just worked out a medley of 10 Beatles songs in a matter of a few days, now that I have adequate knowledge of the OS. IMO, everything (styles, songbook, Helicon, etc) about this board is terrific, but many will disagree with me. Good luck
