About the only kb that doesn't need any tweaking as far as the styles and voices is Ketron. After adjusting the vocal settings I could I just play them.
Haven't done much to the Yamahas either but the e.q. is critical and a lot of the styles parts need to be muted or the volume adjusted.
The Korg PA 80 didn't need a lot but I had to teach it to play a little country.
The Roland G70 only needed overall e.q. to sound good, and not much of that.
On none of these I had to really edit and re-save every style to sound good. And you shouldn't have to. I found on my PA800 I would have to do that to EVERY style. Probably the OS upgrade fixed it though. And a great feature of Korg is that EVERY style CAN be edited or replaced in the factory banks. All keyboards should be that way!
As far as I know only Korg and Ketron do it.
Anyway, if I had Korg PA800 still, that's why I would love it.
