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 ?
