Thank you! The first album/liveset only used GND machines (firmware X.04 at the time), no sampling was involved. In the second liveset (X.05) I used internal sampling a little bit but I believe you can load the sysex into a non-UW Machinedrum to get hold of the synthesised sounds. In the second liveset I also used a variety of MD machines, not just GND.
So both livesets were done with the unofficial firmware.
