Thanks audyaplayer... Lots of great info (i read German)
This still does not answer the question, i have  had from the beginning, will we be able to use the launchpad feature instead of the styles....  Or will it also work like multipads on top of a style?
Not that a 76 key version would be an option for me...  If i ever upgrade my pa4x, it will be for an 88 key version or for a module version...   
But from the features, i would agree this is definately the most advanced arranger ever build (when just judging the arrangement part)
