Diki,
I agree with Spalding and with you, in that you carefully express your educated (and thus, inquiring) opinion, and care about what will happen. And of course you are not raining in anyone's parade. Educated opinions and inquiring minds like yours is the reason I log on the SZ.

If the new super styles on the Audya are very heavily reliant on the new looped guitar parts, they will (as you predict) be a disaster. Like having a band with some mediocre musicians and a guitar wizard that attracts the crowds. Once he leaves the band, they rest will roll into oblivion.

On the other hand, if Ketron programs their styles thoughtfully, and restrain themselves from showing off, the super-duper guitar part will not outshine the rest of the instruments, and the result will be more balanced and player friendly than the one you envision (a few super styles and a lot more "normal sounding").

We are all waiting... for the Audya.

PS, no matter what, I am NOT going to get an Audya anyway. My use of an arranger at home does not justify anything over S900, and even that is maybe too expensive.
