I am also trying to understand how to create new styles on my Audya 4. It does not seem very clear to me how to do that from reading the limited amount of information in the manual.

I am surprised that I have been unable to find even one video of anybody programming a new style. It would make it so much easier to understand if Ketron had produced a few videos showing the important steps of style creation - with some real musical examples! This would encourage users to experiment more with styles.
