As someone who has been and still is basically more Korg orienated than Yamaha I go along with what Gary says. Even my less comprehensive PSR7550 is a great keyboard and in particular its abiiity to load extra new basic samples is a great advantage in this price range. As a matter of fact I only have two wishes, one of which I wrote about to Yamaha and might be fulfilled in time.
First and foremost the Drums, though a lot better are still not in league with Korg or Ketron. But worse than the lesser quality is the fact that you cannot intervene in this area the way you can with the two K"s. I mean on my PA800 I can go to a page and alter the volume, pan, reverb,even cut-off of each individual item in that particular drumset ( bass, snare, hi-hat etc.). This to me has always been of the utmost importance and practical use.
The other thing is that I would wish Yamaha would use the possibility to add 64Mb Sound/Style Packs to create special Packs for those interested in ONE particular sound,for example Piano, Sax, or Trumpet. They could easily provide the Pack with a substantial and very good basic sample ( just one or two)add a few styles for good measure and I for one would be happy to purchase such a Pack, personally with an outstanding acoustic piano.
Other than that ( and of course the lack of a touchscreen) there ain't nothing wrong with these new Yamaha siblings......
Gary, when will you get yours ?

kind regards,
John
