Sculpture Body EQ models in MainStage
All other Body EQ models provide the following parameters:
Body EQ parameters
Formant–Intensity knob: Rotate to scale the intensity of model 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 flat 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 fine structure. A value of 1.0 results in enhanced/full fine 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 difference in your sound. It is highly dependent on several string, Waveshaper, and Body EQ model parameter settings. As always, use your ears!
