I found a newer version of the PC I/F driver at Korg's X5D downloads... now, everything works perfectly well (no system crashes or other ugly things)! Nevertheless, why does my 05R/W not respond to MIDI datas from the soundcard. By the way: the expander receives program changes sent through the soundcard's MIDI OUT. But I checked all MIDI Filters in Cubase, everything's correctly set. I also disabled all MIDI Filters in the 05R/W. Still there it doesn't work... confusing! Thanks!
