Tony, I often wish I still had an Audya, and I may again!. The 76 note version didn't suit me very well. I didn't like the location of the wheels, and I prefer joystick.
I didn't have any problems at all with it, but I don't do the extensive, or intensive, work with external sounds and samples that seem to cause others problems.
Also, I was able to recoup most of my investment after using it from close to two years.
I generally don't keep anything more than a year or two.
The Audya was the best arranger I've ever owned. The BK7m was by far the best arranger for the dollars invested.
I'm still evaluating the PA3X. There's a lot to like about it, with the combination of size, weight, ease of use, features and sound.
