I've said this many times. My experience with the Audya has been a horror story:

Audya 4
* Received with Side Panels loose and broken
* Controls are so compacted on the portable unit, you can easily hit the wrong buttons when selecting various live settings.
* The manual is horrible; I couldn't even figure out how to trigger the damn thing with a controller

Audya 5
* Constant Screen Flicker
* Right side audio output of unit kept cutting in and out requiring a power reset
* Kept getting Exception 1 errors when boot up
* Audio Looping of Drums had discernible gaps
* Non-Existent support from Ketron
* Was not impressed with the acoustic sounds
* Many Styles were lacking (Big Band for example).
* Manual sucks.

Now I know some of those issues above have been fixed, but it has taken over a year for some owners to get this fixed. Release of new styles and sounds has taken over a year. I'm not even comparing the Audya to any other keyboard, just evaluating it from it's own point of view. I felt this board is just TOO risky to be considered for live gigging. It's just not reliable.
