Note: This nonlinear effect 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. In Logic Pro, 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. In Logic Pro, 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. In Logic Pro, 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 effect in Sculpture.
1. In Logic Pro, 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 flat as you play up or down the keyboard,
consider adjustments to the Tension Mod, and perhaps Media Loss, Keyscale parameters.
