Rossum Electro-Music Linnaeus
is a state variable filter that can modulate resonance from zero to negative frequency. The module works either stereo or dual mono. In Dual Mono mode, two different signals are processed with the same settings. The filter characteristic is infinitely variable from lowpass to bandpass, highpass, notch, shelving and other variations. The second highlight of this filter is the Thru-Zero modulation of the resonance, which then achieves a negative direction. To animate the modulation accordingly, the built-in modulation oscillator is used, which has infinitely variable waveforms and follows the cutoff frequency at the touch of a button. Since all relevant parameters are equipped with bipolar attenuators, complex modulations and, above all, filtering can be achieved.
