This action has for effect the duplication of all divisions of an instrument. For example, if a sample linked to an instrument has a keyrange of 36-38, the software duplicates this division so as to have 3 times this linked sample for the keyranges 36-36, 37-37 and 38-38. It makes then possible to thoroughly edit each sample parameter for each different note, instead of editing whole divisions with the same parameters.
It is also possible to duplicate the divisions according to velocity ranges.
