I have loaded the Musikant styles/registrations into my PA3X without a problem (and I think that Don Mason did the same). The styles that give problems are usually the converted ones (especially from Yamaha or Ketron, because they lack important parts, like the SA voices or the audio tracks).
Andrea,I would guess you are correct. I haven't heard anyone else having problems using just the Korg styles. Still when you crash that first time, it stays in your memory for 17 lifetimes!
I like a lot what they did at Korg Germany, to the point that now I have two copies of a few styles or registrations because they have been tweaked in a clever way and sound different, so to me it's worth keeping both versions.
I don't even play my PA3x because the styles are so bad....cha-cha doesn't sound like a cha-cha, no Strauss waltz, polkas are for kids, etc. But, in all fairness I haven't tried any of the Korg download styles from the Korg site.
I have a few Musikant zip files I found somewhere that I haven't opened yet (because of the "crash" I had and because I'm not sure if they are 3rd party or pure Korg files). May I ask where you got a copy of the Musikant files that you're using? I know that with the PA3x versions, Korg allows them to be interchanged. Correct?
I'd love to get back to playing regular again if I can only get some decent styles to work with on this keyboard!
