Hi Grubba99:
Single touch setting (STS)does set 4 sounds for the "right hand", sounds that are suitable according with the style/pattern you selected. Let's say you select the "Ipanema" style, the 4 "functions" buttons under the screen, F1 is flute, F2 is piano, F3 is Electric Piano and F4 is Sax...( I'm doing this by memory, so is not accurate), but you get the idea behind STS.
Hope it helps.
