All I know is my faith, although tested by Ketron and thier crazy PR team, is restored. This is obviously an ongoing feature of the Audya, and every time I look at another I come back to the Ketron, its an entertainers keyboard, the best drums, bass and the styles are perfect for vocalising. Yes I have T4 also, but its use is more the studio, at this stage. Can't wait for the news and demo;s on all of this AJ.. Thanks
