The styles (on pen drive) i bought from Ketron Italy and AJ for my SD90 doesn´t work on Event. I contacted Ketron and they said the problem was the copy protection. The styles I have bought from other manufacturers works fine (though they aren´t always that good from the beginning - as a matter of fact, some of the third party styles are crap).
Ketron said they intend to rework the styles from Audia and SD90/9/60 for Event. And when I suggested a nice price for old custumers, they replied that it would not be impossible.
To be continued...
