•
Tension Mod slider: Drag to set the momentary detuning of the string.
•
Tension Mod High Scaling slider (blue): Drag to set the tension modulation behavior for notes
above middle C.
•
Tension Mod Resolution Low Scaling slider (green): Drag to set the tension modulation
behavior for notes below middle C.
Note: This nonlinear eect can deliver surprising results and can also make the entire
model unstable, especially when combined with low Media Loss and Inner Loss values. If
your sound spikes or drops out during the decay phase, try reducing Tension Mod, and
perhaps Resolution.
Adjust Resolution key scaling
1 Click the Keyscale button.
2 Drag the green low slider inside the top of the Material Pad ring for low notes—or the blue high
slider around the top of the outer ring for high notes.
Adjust Media Loss key scaling
1 Click the Keyscale button.
2 Drag the green slider inside the left side of the Material Pad ring.
Adjust the Media Loss release time
1 Click the Release button.
2 Drag the blue slider in the outer ring at the left side of the Material Pad.
Values above 1.0 cause media losses to increase when the key is released. This parameter can be
used to simulate a string that is dropped into a bucket of water after initially vibrating in air, for
example. Obviously, this is not what the average violinist or pianist would do, but it can be useful
for some interesting sound variations.
Adjust Tension Mod key scaling
Strings, such as those of a guitar, exhibit a particularly prominent nonlinear behavior—if the
string excursion is large, the string is detuned upward. Because this detuning is caused by the
momentary, rather than the average, excursion of the string, the detuning occurs very quickly.
This phenomenon is known technically as tension modulation nonlinearity. Nontechnically, setting
or modulating the Tension Mod slider to values above 0.0 emulates this momentary detuning
eect in Sculpture.
1 Click the Keyscale button.
2 Drag the green low slider inside the right side of the Material Pad ring for low notes—or the blue
high slider around the right side of the outer ring for high notes.
Tip: If your instrument seems slightly sharp or at as you play up or down the keyboard, consider
adjustments to the Tension Mod, and perhaps Media Loss, Keyscale parameters.
