Use Sculpture’s Body EQ models
All other Body EQ models provide the following parameters:
Shift
Fine Structure slider
Intensity Stretch
Body EQ parameters
•
Formant–Intensity knob: Rotate to scale the intensity of the model’s formants. Any formants
(harmonics) in the model become louder or are inverted, depending on how this parameter is
used. A value of 0.0 results in a at response. A value of 1.0 results in strong formants. Negative
values invert the formants.
•
Formant–Shift knob: Rotate to shift the formants logarithmically. A value of −0.3, for example,
shifts all formants one octave downward, 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 knob: Rotate to stretch the formant frequencies, relative to each other.
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), whereas high values move the formants farther apart from
each other. The control range is expressed as a ratio of the overall bandwidth.
Note: When combined, Formant Stretch and Formant Shift alter the formant structure of the
sound and can result in some interesting timbral changes.
•
Fine Structure slider: Drag to enhance the spectral (harmonic) structure, making the overall
harmonic makeup of the sound more precise. This results in a more detailed sound that is
harmonically richer and—depending on the model selected—more guitar-like or violin-like,
for example. In other words, the resonant cavities of the instrument become more resonant—
somewhat like the increased depth of tone provided by a larger-bodied guitar. A value of
0.0 denotes no ne structure. A value of 1.0 results in enhanced/full ne structure of the
selected model.
Note: Heavy use of Fine Structure may be quite CPU intensive. Also note that Fine Structure
may not actually result in much dierence in your sound. It is highly dependent on several
string, Waveshaper, and Body EQ model parameter settings. As always, use your ears!
