Believe it or not the manufactures put out these videos on the web to encourage people to buy their instruments so why should it come as any surprise that these same demos can put people off ? I have heard some incredible demos on the web that have made me want to buy that keyboard . Certainly I will try before I buy but the interest in buying on my case is often piqued by a great demo . If that's not the case for a substantial bunch of people then the manufacturers are wasting a lot of time and money with these demos are they not ?
