seek some type of a demo so that some one can introduce you to style editing and help you to understand how it is different from style creation.

Look I'll let you call it whatever you like. It will always be the mixer page to me and every keyboard manufacture since that's exactly what the mixer page does.
Fact is you asked a question which was this....
Other than the bugs, can anyone articulate how is the Audya a work in progress?
I answered your question and told you straight out that you couldn't make your own styles on the keyboard (amongst other things) because the Style Edit mode doesn't even exists. It's not coming until v4.0
So you can either call me a liar or accept what I'm saying because NOBODY here will jump to your defence and say that they can program their own styles into the Audya.
No sequencer, no sampler, limited sound engine, no style creation mode (called it that especially for you

), lots of bugs, system crashes, hardware fault, and all this is very much so a work in progress with a premium price tag.
Anyone want to beta test ? Will only cost you 5 grand
