So far it seems that the order you press/hold the trigger buttons affects the order of the multiple trigger copy/paste function.
So always press/hold triggers one by one before pressing Copy.
For example lets say you want to copy triggers 1 - 4 to triggers 13 -16
Press and hold one by one triggers 1 to 4 then press Copy (Rec)
Now press only trigger 13 then press Paste (Stop)
If you press/hold triggers from 1 to 4 at the same time, it is most likely that at the paste time triggers will be pasted on a different order.
Have a nive pasting!
