Hi Donny,
haven't been thru them, but a couple of guys over on the korg forums have done utube video's on certain aspects of style creation.
Antony Sharmon has been doing video's on creating a style from a song midifile.
Not the quick conversion function that the pa4x is capable of, but full on creation of style from song.
Another young guy called Sam , has done a number of video's. We came across each other , early days of pa800. He wanted to create styles but didn't quite know where to start. I knew a bit , from there we had a ball for the next year or so .
Probably a bit of a laugh ( maybe even cringe worthy haha) going back thru all those old posts. Still , if I forget how do something, it's probably documented in the old archives over on the korg forum.
Sam has put up a number of video's on how to do certain things. A video is so much easier than describing how to do things. Thank goodness for u tube.
He actually records his own styles. ( from scratch ) No doubt he would have figured things out for himself , he desperately wanted to create his own styles, but it's nice knowing I might have helped speed up the process for him, even if only a little bit.

Just a bit hard to know where to start sometimes.
