Other EQ Models
For all other Body EQ models you have the following parameters:
Formant—Intensity
Scales the intensity of the model’s formants. In other words, any formants (harmonics)
in the model will become louder, or will be inverted, dependent on how this parameter
is used.
 A value of 0.0 results in a flat response.
 A value of 1.0 results in strong formants.
 Negative values invert the formants.
Formant—Shift
This parameter shifts the formants logarithmically. A value of –0.3, for example, shifts all
formants one octave downwards, and a value of +0.3 shifts the formants up one
octave. A value of +1.0 shifts up by a factor of 10—from 500 Hz to 5000 Hz, for example.
Formant—Stretch
Stretches the formant frequencies, relative to each other. In other words, this parameter
alters the width of all bands being processed by the Body EQ, extending or narrowing
the frequency range.
Low Formant Stretch values move the formants closer together (centered around
1 kHz) while high values move the formants further apart from each other. The control
range is expressed as a ratio of the overall bandwidth.
When combined, Formant Stretch and Formant Shift alter the formant structure of the
sound, and can result in some interesting timbral changes.
Fine Structure
This parameter enhances the spectral (harmonic) fine structure, making the overall
harmonic makeup of the sound more precise. This results in a more detailed sound that
is harmonically richer and—dependent on the model selected—more guitar or violin-
like, for example. Put another way, the resonant cavities of the instrument become
more resonant—somewhat like the increased depth of tone provided by a large-
bodied guitar.
 A value of 0.0 denotes no fine structure.
 A value of 1.0 results in enhanced/full fine structure of the selected model.
