4-6b: Dispersion
Dispersion
This models the rigidity of the string. Higher values
correspond to thicker-gauge strings, and increase the
inharmonicity of the string. ("Inharmonicity" means
that the pitches of the overtones become out of tune
with the fundamental.) At extreme values, it will create
bell-like timbres, as if you were hitting a bar of metal.
Dispersion can be modulated by three AMS sources,
which are added to the Dispersion setting.
Character
This changes the way that the upper harmonics
become detuned as Dispersion is increased.
With the Bell setting, as you increase the Dispersion
amount, the lower harmonics will go out of tune
gradually, but the upper harmonics will do so very
steeply. The higher the harmonic, the more out-of-tune
it will become. The resulting inharmonicity is similar
to the sound of a bell.
With the String setting, the upper harmonics will still
become more out of tune than the lower harmonics,
but with a more gradual slope. Up to moderately high
Dispersion settings, this retains a string-like character.
AMS 1
This selects the first modulation source to control the
Dispersion. For a list of AMS sources, see "AMS
(Alternate Modulation Source) List" on page 967.
Intensity
This controls the depth and direction of the Dispersion
AMS modulation.
Intensity Mod AMS
This selects an AMS source to modulate the intensity of
AMS 1.
Intensity
This controls the depth and direction of the Intensity
Mod AMS.
AMS 2
This selects a second modulation source to control the
Dispersion. For a list of AMS sources, see "AMS
(Alternate Modulation Source) List" on page 967.
Intensity
This controls the depth and direction of AMS 2.
AMS 3
This selects a third modulation source to control the
Dispersion. For a list of AMS sources, see "AMS
(Alternate Modulation Source) List" on page 967.
Intensity
This controls the depth and direction of AMS 3.

String Track
String Track Intensity
This controls the overall depth and direction of String
Track's effect on Dispersion. You can adjust the offsets
for each individual string using the String 1...6
parameters, as described below.
String 1...6
These set the individual Dispersion offsets for the six
Strings, as set under "9-9b: Strings" on page 277. For
instance, you might set the lower strings to greater
values, to model typical guitar strings.
These values are also available for modulating other
parameters via AMS; they appear in the AMS list as
Disp. String Track.
