Ok, that's a little confusing, but if I'm understanding you correctly, my response would be that different players have different needs, and as Abacus points out, your needs as a 'pro' may be completely different than the needs of your average 'home player', and if the 'pro's' only make up a tiny percentage of the Arranger market, who do you think Yamaha is going to listen to? Just sayin'.
