I used the SST software that came with the stick. The slider was set to BANDS, then divided into three. I'm not sure of the percentages because I'm at work.
But I think that from 0 to 40% of the band the zoom out key([) is set to it, the center of the band is from 40% to 60% with no key set to it, and the 60% to 100% uses the zoom in key(]).
I believe if you are going to use the SST software you'll need to delete the stick.cfg from AH.
