The manufacturers know who they are selling their instruments to and kit out the keyboard accordingly. It is no secret that yamaha position the Tyros and psr range at home users. Thats why they have a limited VH , stripped down sampler and minimal voice editing capabilities. Home users typically play guess where ????? At home !!!! They usually play for themselves or friends and family, they dont create their own sounds, styles, or samples so dont have need for gigging pro features. Yamaha styles are not too in your face and seem more subtle and simple (presumably because the home user does not want to have to compete with the keyboard styles)

This is the market where yamaha make their money period. There are very many professional musicians who make a great living from this keyboard and use it for its best potential in pro use. If it isnt up to 'par' (something i do not believe is true) then there are an awful lot of musicians out there who use the instrument daily and have made this instrument sound great regardless.

As far as the styles are concerned, it has been said so many times now that you can simply strip down styles as you see fit. All manufacturers could not have made it easier to aedjust styles in live play, especially in regards to korg instruments. I actually love the style programming in the korg range for the very fact that the style programmers assume you can actually play a keyboard and not simply use 1 finger chords !! The preference for progression from simple to complex style prgramming can all be accomodated in any of the main keyboard manufacturers arsenal of styles. Its up to the user how they work with them.
