Hi VMS,
I think it is not so difficult to get the stuff copied. Just hit the EDIT button in an instrument as usual, choose "MAPPING EDITOR". First uncheck "EDIT ALL". Then select the group you want to copy. Then go to SHOW ALL GROUPS and select firstly "SHOW NONE" and secondly after that choose the group you want to copy. Now only one group is selected shown with a little marker on the side.
Also you should see now in the MAPPING EDITOR only the zones of this group which you plan to copy. Okay, now choose in the EDIT MENU of the MAPPING EDITOR the "COPY ZONES". Switch to an empty group and just PASTE these zones to the new group. Voila! Maybe not the most comfortable way, but this is how it works in Kontakt 1.2.
Best, paule.
