I just received my Ajamsonic upgrade yesterday. I also got the Ajamsonic 2 DVD Audya Tutorial. The tutorial was very helpful for getting me up to speed with all the features of the Audya. I don't do well with written manuals and pick up information much quicker by viewing a good video manual.

I have one of the first Audyas' that arrived in the US; no memory expansion, so my Audya takes a few extra seconds to boot up. I have no issues with that but I guess it could be a problem if my Audya would lock up during a performance. The good thing about a Ketron product is it never locks up in the first place. Mine never has.

Very worthwhile upgrade and I highly recommend the product.
