Waveshaping four-quadrant multiplier

Modrwy ('ring' in the Welsh language) is DC-coupled ring modulator, based around a vintage transistor array IC, with waveshaping and wavefolding abilities based on overdriving the inputs. Despite being small and simple to use, Modrwy is full of its own flavour and can be used to modulate and morph any CV or audio source of your choosing.

The output is proportional to the X input multiplied by the Y input, the absolute value of which is indicated by the intensity of the LED on the X input slider. By pushing the slider upwards, the X input is overdriven and the input waveform begins to fold back in on itself, creating unique and complex waveshapes.

Use it as an audio ring modulator with added spice, a tool for creating complex LFO modulation, a bipolar VCA, and much more.

Buy Modrwy from the Dwyfor Tech stores on Reverb or Etsy.
