I think we can all agree that Tony Hughes was the most upset, totally bashing Ketron for months on end.

If you read his comments in the Ketron Forum, he is a very happy customer right now.

He said his Audya is a different keyboard.

"The live drums are larger than life on OS4, if you thought for one minute they were good on Os3.0, they certainly are mind boggling now. I think that Roberts has had a lot to do with OS4 even though he lives in Canada and Ketron in Italy, the World isn’t that big anymore with the Internet. If he has had much to do with Audya he’s done an excellent job of it, this is not the same keyboard I bought last year, and it’s moved up 5 gears!
If you close your eyes and listen to Robert playing the Audya its sound like it says on the button, but 100 times better. "

So is it worth it ?
