Waveguide
play six notes creating individual glottal pulses and breath noises, which will then
all go through a single formant filter.
Input Trim
0-100. This sets the input level to the formant filter. If the filter resonance is high,
you may need to turn down the input to prevent clipping.
Formant Shape
These parameters assign vowel sounds to the minimum, center, and maximum
values of the manual control, the Shape X-Fade controller, and the LFO. For
example, let's say that Mod Wheel is selected as the modulation source, and Voice
Top is set to a, Voice Center is set to i, and Voice Bottom is set to u. Moving the
wheel up from 0 will then produce the vowel sounds "u", "i", and then "a."
Bottom
a, e, i, u, eee, straight. This is the vowel sound at the minimum value of the
controller. "Straight" means that the glottal pulse and breath noise will be heard
directly, without any formants.
Center
a, e, i, u, eee, straight. This is the vowel sound at the middle value of the controller.
Top
a, e, i, u, eee, straight. This is the vowel sound at the maximum value of the
controller.
Vocal Size
Small, Normal, Big. This controls the size of the throat creating the formants. Small
is like a small child, Normal is like an average-sized adult, and Big is like a very
large man.
Damping
0.0-100.0. This sets the amount of high-frequency damping within the formant
filter.
Resonance
0.0-100.0. This sets the intensity of the vowel resonance. Higher resonance settings
will add more character to the sound.
Formant Control
Manual
0-100. This sets the initial position within the Formant Shape, between the bottom,
center, and top positions.
Shape X-Fade
List of Modulation Sources. This sets the modulation source for controlling the
formant shape. For a complete list, please see "Modulation Sources" on page 2.
