My Audya had a problem with the soundboard. It started emitting a loud squeal under all conditions.
I installed 3.0, which I got from AJ, in an attempt to see if that would fix it, but it obviously was a hardware problem.
Since the new OS didn't fix the problem, I didn't spend any more time with it until I got the replacement. I elected to wait for the new shipment of keyboards to arrive from Italy.
I didn't get a chance to see much of what 3.0 addressed. It did have new styles loaded and from what I could tell, allowed the use of dim and aug chords with the audio guitars. It was hard to hear over the squeal.
This was the second Audya I received that was damaged. Both were shipped via UPS and both had holes in the side of the carton.
I took pictures of both boxes. On the second one you could actually see the music rack showing through the hole.
I don't know if this caused the problem, but I wouldn't ship a ball bearing by UPS.
