If you want to sell your arrangers to the homeplayers, then these Yamaha demonstrators are the way to go...
So why don't you think these would equally appeal to pro players? I'm a pro player and these sort of demos certainly impressed me to buy one.
I always keep wishing for a demo aimed more at pro's (most of them do music nothing like what I do) doing more contemporary approaches.
How about Harris' more contemporary examples in the Namm vids I posted? When you say contemporary, you mean 2011 hits or? What's contemporary to you afterall could be consiered old school to another. Please provide examples, perhaps your own arrager created tunes.
