The "Throat Formant" parameter controls the characteristics of the simulated
player's lungs, trachea, and oral cavity. Can add a realistic "roughness" to the sound.
The "Controller" parameter specifies the controller to be used for throat formant
control. When set to "off" no throat formant variation can be produced, but an absolute
throat formant value can be set via the "Value" parameter, below.
Depth
≤
-127 ... 127.
Sets the amount of variation produced by the controller assigned to throat formant.
The higher the value the greater the variation. Positive values cause an increase in throat
formant effect in response to higher controller values (e.g. increased breath pressure or
higher modulation wheel position), while minus values cause a decrease in throat formant
effect in response to higher controller values. The "Depth" setting is reflected in the
graph to the right of the parameters — the horizontal axis represents the controller value
and the vertical axis represents throat formant depth.
Curve
≤
-16 ... 16.
Determines the relationship between the controller value and throat formant depth.
When set to "0" the relationship is linear. That is, a change in the controller value
produces a corresponding change in throat formant depth. As the curve value increases
the lower end of the controller range has relatively little effect on the sound while higher
controller values produce more dramatic changes. Negative curve values have the oppo-
site effect: the sound changes dramatically at low controller values while higher values
produce relatively little effect. The "Curve" setting is reflected in the graph to the right
of the parameters — the horizontal axis represents the controller value and the vertical
axis represents throat formant depth.
Value
≤
0 ... 127.
Determines the amount of throat formant effect produced when the "Control-
ler" parameter is set to "off". The higher the value the greater the effect.
• No throat formant effect can be applied via any controller if the ELEMENT
