hello Chicken fry,
There are only few people in this forum that create "normal" (midi) custom styles and there are even less (probably none) that make audio styles. Reasons why's that are obvious, I guess: it requires quite a knowledge and is very time consuming. Besides that, normal styles are more flexible to use and can also be easier transferred/adapted to another keyboards than that's the case with audio styles.
My keyboard doesn't support audio styles and even if it did, I probably wouldn't make them.. because making good midi style can be challenging enough
To summarize: it's not that members here are not willing to share... probably there's nothing to share.
