VCV Random is the hardware version of a well-known classic from the VCV Rack fundamental library. A random CV generator with 4 types of randomness and a triggerable sample-and-hold function.

Sliders allow you to set the internal clock tempo (RATE), shape the probability of triggering (PROB), blend old with new values (RND) and set the shape of all four random outputs (SHAPE).

Internal random
clock source

Whenever the clock activates, the RATE slider’s light flashes. At the same time, there’s a chance that the internal random source will create a new value, depending on the PROB slider’s setting.

If it does create a new value, the PROB slider’s light flashes too, and a pulse comes out of the TRIG output.

External IN & TRIG inputs

If the TRIG input is patched, the RATE slider is ignored, and the internal clock is only triggered when an external trigger is received. The PROB slider is used to filter this trigger by applying some probability.

If the IN input is patched, this external voltage is used instead of a random voltage upon each trigger. The RND slider has no effect.


Thanks to a switch in the back of the module, you can normalize the LIN output to the 4 CV inputs and adjust the amount of modulation for each parameter with the attenuverters.

This adds another layer of randomness to your results, enabling more dynamic and unpredictable outcomes.

SHAPE Outputs

The STEP output jumps to the new value in one step at 0% SHAPE, and divides the transition into 16 steps at 100% SHAPE.

The LIN output immediately reaches the new value at 0% SHAPE, and takes the whole clock cycle to do so at 100% SHAPE, staying constant in between.

The EXP output shifts exponentially, becoming linear at 100% SHAPE, with its pace adjusted by the SHAPE slider.

The SMTH output transitions smoothly, with the speed controlled by the SHAPE setting, holding at the target until the cycle ends.
