Media Loss Release
The blue slider (in the outer ring of the Material Pad) controls the Media Loss Release
time. To activate it, you must first enable the Release button, to the bottom right 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 a number of interesting sound
variations.
Tension Mod (Morphable)
Strings, such as those of a guitar, exhibit a particularly prominent nonlinear behavior: if
the string excursion is large, the string is detuned upwards. As 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 non-
linearity. Non-technically, setting or modulating the Tension Mod parameter to values
above 0.0 emulates this momentary detuning effect in Sculpture.
Please note that this nonlinear effect can produce some surprising results, and can also
make the entire model unstable, especially when combined with low Media Loss and
Inner Loss values. So, if you have a sound that spikes or drops out during the decay
phase, try reducing Tension Mod (and perhaps Resolution).
Tension Mod Scale Low and High
Allows independent adjustments to tension modulation key tracking, for notes above
and below middle C (C3). The green low slider (down to C0), inside the Material Pad
ring, is visible when the Keyscale button is enabled. To adjust, click-hold, and drag. The
blue high slider (up to C6) runs along the left-hand side of the outer ring. Click-hold,
and drag, to adjust.
Note: If you find that your instrument seems slightly sharp or flat as you play up/down
the keyboard, look at making adjustments to the Tension Mod and perhaps Media Loss
Keyscale parameters.
