Wow, It is hard to believe this is the same keyboard in a prior demo..A skilled player makes the difference with guitar work..The demo shows off the apparent strenghts, namely guitar and brass sounds, as well as nice drums and styles..They did not show the piano much[maybe it is still Korg piano, that would be a bummer]..I disagree with Terry, the sounds illustrated in this demo blow the Tyros away..With the probable better vocal harmonizer and MP3 player[option], this could be the best unit for the stage and studio. We will have to see the weaknesses before we embrace it as the "BEST"..BTW, as you all know I am not a strong Korg fan, but they have my initial attention...Can't wait to see what Roland has on the drawing table,,hopefully they are paying attention to the other guys..
