Freq Shifter
This unusual effect is sometimes called “spectrum shifting” or “single sideband
modulation”. Frequency shifting shifts every frequency 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.
