According to the User Manual (page 229 in the English version) to Copy a rack item from one channel to another use basic Drap&Drop, and to Move a rack item from one channel to another use ALT/Option + Drag&Drop. This works for EQ settings but not for Inserts. For inserts it is reversed - basic Drag&Drop Moves a rack item and ALT/Option + Drag&Drop Copies it!
I can not seem to copy or move Send rack items at all.
Why do these inconsistencies exist?
Is there a good reason for the confusion?
