Tony, sorry it didn't work out.
I experienced the same thing with Korg PA800 when it first came out. I spent untold hours trying to make it work, but it never got close. I sold it before they updated the OS. I had to if I wanted to keep my job.
I've been so busy that I haven't had a lot of time to spend on setting the Audya up yet.
I haven't experienced the really bad problems you've had, although it is sometimes infuriating to wrestle with the manual.
I noticed you had 3.0B. I only have 3.0A, so you must have a Beta copy.
So far mine has not frozen up at all. Yes, there are some idiosyncrasies in some of the screen selections and controls, but they haven't been deal-killers.
I'm currently fighting the mic processor to get it like I want it. I have been really spoiled by the wonderful automatic processing of the Harmony M and I want the Audya to sound like that too. I'm getting closer.
Maybe by Tuesday I'll have it ready enough to take to the job.
