Worng Electronics Parallax

Stereo VCF with independent L/R frequency and resonance skew

16 HP Eurorack module

Parallax is a stereo voltage-controlled filter with roots in the Sequential Circuits Pro One and Prophet 5 rev 3 topology, extended with independent skew controls that let you offset cutoff frequency and resonance between the left and right channels. It offers both -12dB/oct and -24dB/oct outputs simultaneously, making it a powerful tool for creating wide, animated stereo filter effects from mono or stereo sources. Its playable design with multiple FM inputs, attenuvertors, and CV-controllable skew parameters gives it a rough yet creamy character suited to everything from subtle stereo width to chaotic self-patching mayhem.

Features

  • Stereo VCF based on Sequential Circuits Pro One and Prophet 5 rev 3 topology
  • Independent -12dB/oct and -24dB/oct outputs for both left and right channels
  • Stereo Frequency (Freq) control sweeps both channel cutoffs simultaneously
  • Stereo Resonance (Res) control from flat through self-oscillation to amplitude control of oscillation
  • F. Skew control offsets cutoff frequency between left and right channels around the Freq base point
  • R. Skew control offsets resonance between left and right channels around the Res base point
  • FM1 unipolar CV input with attenuator for stereo frequency modulation
  • FM2 CV input with attenuvertor for stereo frequency modulation (off at 12 o'clock, positive CW, negative CCW)
  • F. Skew CV input with attenuvertor for voltage control of frequency skew
  • Res CV input with dedicated CV amount knob
  • R. Skew CV input with attenuvertor for voltage control of resonance skew
  • Left input normalled to Right input enabling mono-to-stereo patching
