Current version is v1.01 (2010/09/09). - made with SDK 5.10 - for Usine 5.10 and above

Filter Pack comprises a number of audio filters created as user modules for use with Usine

• Butterworth: Resonant filter with a frequency attenuation of -24dB per octave. The Butterworth filter is designed to have a magnitude response that is maximally flat in the passband

• Moog: Resonant filter with a frequency attenuation of -24dB per octave. The Moog filter is based on the four-pole ladder topology developed by Dr Robert Moog in the late 1960s

• Double Resonant Moog: Resonant filter with a frequency attenuation of -24dB per octave. This is a version of the Moog filter above in which the ladders have been ‘detuned’ to provide two resonant peaks tuned a perfect fifth apart.

• Biquad: Resonant filter with a frequency attenuation of -12dB per octave. Provides lowpass, highpass, bandpass, notch, allpass, lowshelf and highshelf configurations using coefficients taken from Robert Bristow-Johnson’s cookbook.

• State Variable: Resonant filter with a frequency attenuation of -12dB per octave. Simulataneously provides outputs for lowpass, highpass, bandpass and notch outputs with the CPU usage of just one filter. It is oversampled 4x internally to provide additional stability upto Nyquist

• State Variable EQ: Creates a three-band EQ out of a single state variable filter. This provides a quick way to manipulate your sound using minimal CPU usage
