Superbooth 2023: AtoVproject - cDVCA - Gaeto

video upload by sonicstate

"We spoke to Marios from AtoVproject at Superbooth 2023, where they showcased their latest Euro rack module, cDVCA. This 6 HP module features a square wave oscillator inside the VCA which tracks volts per octave, and a low pass filter to tame the signal. The drive knob allows for control over the amount of distortion from the internal oscillator or the original signal, resulting in a full voice with the oscillator, filter, and VCA all in one module.

Marios also demonstrated the Gaeto, a clock divider and sequencer available for 80 Euros. The Gaeto has two channels and a knob for determining whether it divides to two or three, allowing for clock divisions, flip flop gate triggers, and quantization of finger beats. The Gaeto also has a pulse output related to the input signal and is available for purchase now. AtoVproject teased a new oscillator in development, with more information to come in their newsletter.

cDVCA Price: 220 Euros

Gaeto Price: 80 Euros"

Eurorack distortion comparison - January 2023

video upload by John Schussler

"I used to number my distortion comparisons, but there are so many now, and in different forms, that I've decided it'll be easier to just go by date.

Here's the January 2023 batch. All have been released fairly recently AFAIK.

The comparison is a little tilted in that some are just drive circuits, while others are full on distortion/clippers. But I prefer to think of it as comparing along a range vs. a head-to-head evaluation.

Note that the video goes from soft to loud at times, because, y'know, distortion, so I recommend not blasting it too loud until you've skipped around a bit to get a feel for the dynamic range.

VCO is an Acid Rain Chainsaw saw wave. Envelope: Zadar. Sequencer: Stochastic IG.

Small Tube VCA/Distortion Modules

video upload by John Schussler

"There seem to be more and more folks making modules with small tubes these days. I have a few of them, and figured I'd do a comparison. These are all 'distortion' modules in one sense or another. Some are VCAs, some are filters, and some are just tube-y grimy-ness.

I've also thrown in an intro to the cDVCA, a new kind of VCA that is also a specialist at distortion. It doesn't have a tube, so it gets a solo spot at the end.

[SOUNDMIT 2022] ATOVPROJECT cDVCA : VCA Classe D avec distorsion et filtre

"Arthur de AtoVproject présente le cDVCA, un VCA très particulier doté d'une distorsion très typée couplé à un filtre. Sous certaines conditions, le module peut aussi agir comme un oscillateur. Plus d'infos : https://atovproject.de/products/cdvca"

Unique VCA that’s also a wave shaper, overdrive, and filter - With AtoV project cDVCA

video upload by Monotrail Tech Talk

"The brand new AtoV project cDVCA is a module inspired by class D amplification. It can be used as a regular VCA, but the clever design makes it also suitable as oscillator, synth voice, wave shaper, overdrive, distortion, and simple filter. In short, it’s a VCA that’s actually a complex sounds design tool!

In this video I explain how the module is operated. But I mostly focus on a series of patches and audio demos using the cDVCA as synth voice, sound design tool, and audio processor.
