Hi Marcus,
I know what you meant.
On my PSR-S970, there are 2 ways of browsing available styles similar to the Tyros models:
1. By turning the Data dial, an outlined cursor follows the turning of the dial on the styles - good for intra-page browsing.
2. By pressing the buttons below the screen corresponding to the style pages, P1, P2, P3 etc. - good for both intra-page and inter-page browsing.
So, on Genos, we loose option 1, and we can see it as a compatibility bug. Under current firmware 1.10, our only option is to use option 2, page browsing.
Thanks,
Paul
