Hi my friend,
AJ knew about these problems for a long time. He has not bothered to look into it, so I won't even waste his time. Sorry if I sound negative, but I AM!!!
My styles should play on any other Audya - best is to give it a try. One person even plays them with the latest OS installed on his Audya although I would not risk updating the OS on mine from OS52A that I currently use.
I was planning to create over 3000 (yes, I know that is CRAZY but I was going to go for it anyway) new high quality styles so that I could use this money to purchase a new SD9. However, at this stage, I am considering packing my Audya away and focussing all of my efforts/attention/energy on the Yamaha. I have NEVER!!! encountered similar problems on any of my Yamahas.
All the best my friend,
Make sure you'll fly forever!
