I wonder about the Audya, they are pushing it at the last two shows, but its still a prototype. I worry about them rushing it in to production then once its released it has many problems. The SD1 had so many bugs, then it was updates after updates. The xd9 & Sd5 also has bugs. I've owned all of the Ketrons starting w/MS50 and I just recently sold my SD5 for a yamaha s900. I would take a lot of convincing for me to go back to ketron. They have best sounds but fell behind on compared to yamaha tyros 2, korg PA800, etc.
