QUAD RESONATOR is based on four parallel comb filters that can add tuned resonances to any input signal. Comb filters create a “metallic” ringing effect and are created by feeding a sound back into itself and mixing the two signals. The positional relationship of the mixed signals effects the resultant pitch, resonance, and “springiness.”


    Controls the mix of the dry signal and the processed (wet) signal. The percentage indicates the amount of the signal that is wet.
    Range: 0 ~ 100%
  • PITCH 1, 2, 3, 4
    Controls the pitch offset of the Resonators in relation to the note value.
  • NOTE
    Reference pitch from which PITCH 1–4 knobs will be offset.
    This knob controls how much of each Resonator’s output is fed back into itself. The higher the setting, the more resonant the results will be.
  • +/-
    This switch controls the direction in which signals are delayed before they are added to the input.


  • LEVEL 1, 2, 3, 4
    Controls the level of Resonators on Page 1.
    Controls the overall level of Resonators 1-4.
    This knob affects the pan positions of each of the four Resonators. At the minimum value, all four Resonators are panned to the center. At the maximum value, Resonators 1 and 3 are panned full left and Resonators 2 and 4 are panned full right.
  • TONE
    This knob controls the cutoff of a 6db LPF applied into the internal feedback loop of the Resonators, providing a damping result. At the minimum setting, the sound will be darker and at higher settings, brighter.
