We don't charge for OS upgrades in the UK Robbo, they come from Ketron Italy and are free to download.
Have you spoken to your distributor about possible issues with your Audya? I can give you their phone number if you like?

HiTWD, I wish there was a Ketron Aussie, if the dealer is "Gospel Piano's in NSW, Australia, they seem to be more in the dark than I am with understandinf the issues and faults that lie within. I love the Audya, have fixed some issues myself, but i notice in AJ's upgrade the issue of timing glitches was addressed and fixed for a price. I think Ketron should release a free upgrade for this obviously a bug, and do it asap please.
