If I had the funds right now for the best top end arranger, this would be a deal breaker for me in deciding what to buy:

I made the most awesome styles for the Audya. Someone installs them on his SD9 with catastrophic consequenses. Some even freezes his unit.

I've made the most awesome styles on my BABY Yamaha PSR S770 using my own custom grouped voices from various add on packs found on the internet. Someone installs this highly modified pack on his Genos along with ALL of the new modified styles and everything works perfect right out of the box!!!

I will now put the Audya away for awhile and focus all my attention on my Yamaha. If I itch, I can always dust it off again. And if a miracle should happen, a Genos would find it's way to me.
