These change frequencies in multiplies so a 2X shift makes 400 Hz become 800 Hz and 10,000 Hz becomes 20,0000 Hz. This has the effect of pitch-shifting lower frequencies more dramatically than higher ones, and so, it's not the same as a traditional pitch change from the Sampler Channel, Pitcher or NewTone. For instance, if the shift is 100 Hz, 400 Hz becomes 500 Hz and 10,000 Hz becomes 10100 Hz. Frequency Shifter is a special effect that shifts all frequencies by the same amount.
