Resonant Quadruple Lo-Pass Gate

Vactrols are back to life in a modern way!

RQLPG is a reinterpretation of the classic west coast circuit in a modern way to offer today’s musicians the thrill of using a sacred monster in the most faithful form of the original.

It contains four independent paths, for four sound sources, that can work as:

• Gate acting on the amplitude of the passing signal, like a voltage controlled amplifier,
• Lowpass attenuating the signal in amplitude and at the same time, eliminating the acute ones.

Controls:

• – CV OFFSET pot for defining the Level / Gate or Frequency / Lowpass value.
• – RESONANCE pot adjust the amount of Resonance without attenuating the passing signal by phase inversion.
  Without audio input it can resonate in self-oscillation if pushed beyond the limit.
  We will therefore have a sine controllable in tension and pitchable through the CV OFFSET parameter to make percussive sounds and an indescribably versatile and powerful kick drum.

Inputs and outputs:
Each channel has audio input, output connections and a CV input for control the CV OFFSET pot
