Selling my AtoVproject cDVCA, silver panel, AS NEW. Instead of a standard clean amplifier, it turns your signal into an ultrasonic PWM wave (~34kHz), then lets you drag that PWM frequency down into the audio range and control it via 1V/oct so you get wild, melody-tracking waveshaping instead of a boring volume knob. Add in the Drive stage for a very defined, non-fizzy clipping character, and a 1-pole VCF after that to tame (or lean into) the harmonics. With nothing patched in, it'll even generate its own square wave, so it can work as a mini synth voice on its own (VCO→VCA→VCF in one module).

Not a transparent VCA by design — it's got a ton of character, great for adding grit to oscillators, drums, or just fattening up a thin signal.

Class-D amplification technique is known from “HiFi” amps. It converts an audio signal into a high-frequency PWM-signal, scales it and converts it back again. It aims to be relatively artifact free….but…cDVCA lets you toy around with this process. The frequency of the PWM-signal can be modulated or sequenced with the 1V/oct input and lowered into the audio (sub-20kHz) range. This is something definitely not desirable in normal class-D use and gives you a highly unusual method of waveshaping your signal. With the Drive knob you can dial in some clipping by messing with the class-D process. All of this sounds brilliant in all registers and sometimes incredible harsh. The gentle 1-pole Filter just before the Output lets you tame the results and is - same as all other parameters - CV-controllable. With this module, class-D should stand for classy distortion.
