A hub for your modulations

  • Scale, invert and offset up to four modulation signals.
  • Mix up to four CVs or audio sources.
  • Multiply (ring-modulate) two audio sources, with adjustable carrier rejection.
  • "who can do more can do less": each channel can be used as a plain VCA.


  • All inputs DC-coupled.
  • All inputs handle audio-rate signals.
  • Input impedance: 100k for all inputs.
  • CV offset range: +/- 5V.
  • Gain scale: linear, a +5V CV translates to a gain of 1.
  • Gain range: +/- 2.
