The Cubic Module
Transforms its input signal by offsetting, scaling, squaring, and cubing it.
Cubic calculates the function:
 y = ax^{3} + bx^{2} + cx^{1} + dx^{0}
which (because x^{1} = x and x^{0} = 1) can be written as:
 y = ax^{3} + bx^{2} + cx + d
Take care when applying Cubic to an audio signal.
WARNING: Cubic can emit voltages far outside the safe audio range (5 to 5V). See the usage guide for details.
WARNING: The x^{2} and x^{0} knobs can generate a very large DC bias. See the usage guide for details.
Controls

IN: The gain to apply to the IN signal to produce the value of x for the equation. The range is 0 to 2.

x^{3}: The amount of x cubed to add to y — the a coefficient for the ax^{3} term of the equation. The range is 2 to 2.

x^{2}: The amount of x squared to add to y — the b coefficient for the bx^{2} term of the equation. The range is 2 to 2.

x^{1}: The amount of x to add to y — the c coefficient for the cx^{1} term of the equation. This acts as a attenuverter with a range of 2 to 2.

x^{0}: The constant to add to y — the d coefficient for the dx^{0} term of the equation. This acts as a DC offset with a range of 10 to 10V.

OUT: The gain to apply to y before sending it to the OUT port. The range is 0 to 2.
Ports

IN: The input signal to transform.

OUT: The transformed signal.

CV: A control voltage signal to modulate the associated parameter.
Using Cubic
 Cubic excels at transforming a simple modulation signal, such as a sawtooth or triangle wave, into something more interesting.
 To generate a constant voltage, adjust x^{0} and leave all other controls at 0. The range is 10V to 10V (which you can amplify using the OUT gain).
 To use Cubic as an attenuverter, adjust x^{1} and leave all other controls at 0. The range is 2 to 2 (which you can further amplify using the OUT gain).
 By default, all of Cubic’s controls are set to 0. While this makes the default patch essentially useless, it does make it easier to set any control to 0.
 WARNING: Cubic can generate voltages far outside the safe audio range of 5 to 5V. If you apply Cubic to an audio signal, adjust the IN and OUT gain to keep the output signal in the safe audio range.
 WARNING: The x^{2} and x^{0} controls can generate a signficant DC bias. If you apply x^{2} and x^{0} to an audio signal, adjust the IN and OUT gain to keep the output signal in the safe audio range (5 to 5V). The x^{2} and x^{0} controls can each, to some extent, compensate for the DC bias generated by the other.
