I want to give some feedback on the new OS version:

General impression:
-------------------
Had no problems with the new version so far, it seems at least as stable as the version before. Still a little bit upset that the user live guitar selection is still not working.

(Complaining on a high level as I do not really use this function but I don't understand this as it is perfectly repeatable and a lot of users complained that already )

I'm not sure but I have the feeling, that Ketron has rebalanced some the styles in a positive way.


New styles:
-----------
Congratulation, they are excellent
The XD styles are also well balanced and optimized for the Audya, the only drop of bitterness is the location of all
the XD styles: Unplugged section within the User styles.

Midi accordeon support:
-----------------------
Yes, they did it!!!
Now, more than 2 years after the first release, my accordeon is now supported like on the XD3, I'm very happy, I'm now able to play w/o XD3. It is the interaction with the bass even if it is auto bass.

There are still some minor issues if you play manual bass, but it is ok.
