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.
Please note that heavy use of Fine Structure may be quite CPU intensive.
You should also note that the use of Fine Structure may not actually result in too much
of a difference to your sound. This is dependent on the Waveshaper and Body EQ
modes, plus other String parameter settings. As always, use your ears!
Adjusting Model
You can directly control the model by click-dragging in the Body EQ graph:
Click-dragging vertically on the graph allows you to control the Formant Intensity
parameter.
