Freq Shifter
This unusual effect is sometimes called “spectrum shifting” or “single sideband 
modulation”. Frequency shifting shifts every harmonic in the signal by a fixed number 
of Hz which causes the harmonics to lose their normal relationship. The more common 
pitch shifter, in contrast, preserves the harmonic relationships of the signal and so is 
better suited to creating “musical” harmonies.

You can also type in 
exact frequencies to a 
resolution of 1/10 Hz.
This isn’t to say that the frequency shifter can’t be used musically. Small intervals of 
frequency shifting (1 Hz and below) can produce a wonderful, lush chorusing or 
phasing effect. For bizarre frequency shifting effects, simply crank up the frequency 
knob. Frequencies can be shifted up or down by any specified amount from .1 Hz to 24 
kHz. You can also shift pitch up on one side and down on the other if you wish.
