Has anyone done any serious voice editing on the 4X? If so, any results to share?

Near as I can tell from reading my 4X manual, (and exploring the 4X)Korg has supplied the 4X with all the tools anyone would need to modify a voice to suit; or for that matter to create a desired voice.

I would love to re-create the Hawaiian guitar I hear on my S970...among other voices. I’m convinced Korg has supplied the tools(including sampling)on my 4X. Thing is, I need more instruction.

That said, I’m somewhat technologically minded, but need a bit more info. For instance a class on how oscillators for music sound works would be helpful.
