Hi Sokratis!
I'm sorry, but I don't understand your opinion!
In fact this function is part of AUDYA (the menu is there).
What Ketron is doing is not providing the software for users (like me) to apply the drum sounds of other brands (Korg, Yamaha, ...) in Audya's styles, making their sound (even) better!
I think if it were possible to mark Ketron would benefit ...
Greetings!
