Psychedelic Voltage Processor - four-channel chaos Eurorack module - Random Voltage Generator - 8hp

The Psychedelic Voltage Processor, or PVP, is a four-channel chaos module. It uses color-changing LEDs to produce fluctuating voltages in response to the Channel input, with each channel normalized in series to create increasingly chaotic “taps” that can be used one after another for different variations.

Any positive voltage input such as unipolar LFOs, envelopes, stepped voltages, or simply the onboard normalized voltage patched to a channel input is reproduced approximately on each channel output, with the PVP inducing unpredictable fluctuations due to the variable current consumed by an LED circuit with a mind of its own.
