Sorry to break in here, but a quick answer... It is not illegal to convert a style FOR YOUR OWN USE on another arranger, but it IS illegal to post those converted styles publicly (and several sites have had to remove these conversions at the request of the manufacturer).

Secondly, it is a different matter to clone the sounds themselves, so that they work of conversion is avoided...

That what you wanted to hear...?
