Hi Dennis,
have you found any brand of keyboard that has styles to suit the oz rock bands?
If I rememember correctly the sd1 styles didn't really suit either. Did any of the psr styles work for you.

BIAB has heaps of rock styles with it's supa or mega paks, but again I wouldn't know if any of them would suit. Have you checked out BIAB's demo's?

best wishes
Rikki
