Editing the Hard tune effect
While in the Voice Preset > Filter & Hard Tune page, you can program the
Hard Tune effect.
This effect is a pitch corrector that has been optimized to produce corrective
pitch correction as well as obvious effects made popular by a number of art-
ists. It only works when a chord is recognized.
Choosing the Hard Tune set
▪ Use the Set pop-up menu to choose settings for the Hard Tune block.
Editing the Hard Tune parameters
▪ Use the Rate parameter to specify how fast the algorithm pulls you toward
scale tones. A value of 0 is off and a value of 100 is instant resulting in
something like the infamous ‘Cher’ effect where the pitch correction effect
is stair-stepped and obvious when using non-chromatic scales (those with
at least a whole tone jump between most of the scale tones). Usually, values
around 20 yield acceptable results for smooth, corrective pitch correction.
▪ Use the Shift parameter to set the relative shift in semitones above or below
the input vocal. This is useful for transposing or creating character voices
while simultaneously pitch correcting.
▪ Use the Window parameter to specify how close to a valid scale note you
have to be before the algorithm corrects you. For example, a value of 80
cents means that only when you are singing within +/- 40 cents away from
the target scale note will you be corrected. The maximum value is 600 cents.
In a Major scale having no more than 100 cents on either side of any scale
tone a setting of 200 would result in fulltime correction activity.
