In reality this demo means nothing, ....personally I can make any of the existing arranger Kbs on the market of ANY brand sound great in my hands playing,...cocky? No,...just confident in my abilities and experience as a pro player. Too much emphasis on what it sounds like in a demo vs your own talent and what you can make it sound like as a player and your talent to do so. There is no substitute for playing talent period, And thats all that matters first lets be honest here.
