That's backwards. You multiply the base by 13 and divide by 16.
The tune offset helps to create the psychoaccoustic (and mathematical) phenomenon called beating (see http://en.wikipedia.org/wiki/Beat_(acoustics) ).
This technique is also used by orchestras, when the various violins in a section will slightly detune their individual instruments to create a thicker texture. So you can see how this would make sense, since pad sounds are often an attempt to mimic a strings section.

Sounds great. So basically in the case of 13/16 I should multiply the base frequency by 16 and then divide by 13? What does the fine tune offset do?
