Pitch Shifter
This effect type shifts the pitch of the input signal by a fixed amount. This creates
a thickening effect similar to the difference between a 12-string and 6-string guitar.

Pitch Detune
This effects detunes the pitch of the input signal by + or - 99 cents. A cent is 1/100 of
a semitone. A pitch shift of +99 cents applied to a C natural will make it sound as
a C sharp. The input signal is not split, therefore if you want to create dissonance,
you must route the input signal to the outputs and blend them together for the
desired effect.
Ring Modulator
This generates an outer-spacey, metallic, distorted version of the input signal by
modulating it against an internally-generated digital oscillator. This shifts the
frequency spectrum upwards or downwards depending on the setting of the Spectrum
Shift parameter. For example, if Spectrum Shift is set to +100, the input and all its
harmonics will be shifted up nonharmonically by 100 Hz.
Triggered Flanging
The new Mono Trigger Flange and Stereo Trigger Flange effects (Pitch function) are
identical in every way to their original counterparts (Mono Flanging and Stereo
Flanging, respectively) except that they both provide an additional function: they
can be triggered to produce a sweeping effect. Three additional parameters have
been added to make this possible.
Retrigger Point
The Retrigger Point parameter (Parameter mode, Page 2) determines at which
point in the Flanger effectÕs cycle it should begin when triggered. This can be set to
a value between 0 and 255. On the Mono Triggered Flange, a value of 64 will produce
a downward sweep.
