Dual VCA with CV Attenuators, Offset Control, Variable Curve, and optional summing - the perfect general purpose VCA!

VCAs are a critical building block for any modular system. The small 6hp size makes this module great for small cases, but a compact two channel VCA can always be a useful addition to any larger case. This module was adapted from a design by David G. Dixon.


  • Continuously adjustable curve response from linear to exponential.
  • Gain trimmer with above-unity gain
  • Dedicated CV attenuators
  • LEDs for monitoring CV signal
