Exploring the Wild Possibilities of Atovproject's CDVCA: The World's First Class-D VCA with 1V/Oct Tracking

Atovproject's CDVCA module is a game-changer in the world of VCAs. This innovative module introduces a unique approach to VCA technology based on Class-D amplification, offering a completely novel concept that has inspired a new generation of VCA designs. Atovproject's CDVCA module is the world’s first Class-D VCA that features 1V/oct tracking, delivering crazy waveshaping abilities that track your melodies in a way that you wouldn't have thought possible.

The module converts the input signal into an ultrasonic PWM signal, which it then scales and filters back down to the original signal. This unique approach to VCA technology allows for incredible versatility in shaping sounds. The PWM frequency can be lowered down into the audio spectrum, and the frequency can be controlled via its 1V/oct input, opening up a whole host of creative possibilities in modular synthesis.

The CDVCA module's drive control features an innovative clipping method that does not rely on overdriving any circuitry, resulting in distortions with a very defined character. This method offers a unique approach to shaping tones, and the distinct character it produces is highly sought after by producers and sound designers looking for something different.

The CDVCA module's 1 pole VCF/tone circuit allows you to keep things under control. The harmonics produced by this module can be aggressive, so this feature provides a level of management to keep things in check where necessary. However, the harmonics it generates can be a great tool for adding texture and complexity to your sound.

Another great feature of Atovproject's CDVCA module is that with no input, it generates a simple square wave, making it a suitable tool for creating a simple synth voice (VCO->VCA-VCF).

In conclusion, Atovproject's CDVCA module is a unique and innovative product that brings a whole new level of creativity to modular synthesis. It offers an innovative approach to VCA technology that allows for incredible versatility in shaping sounds, and its 1V/oct tracking abilities create previously unimaginable possibilities in waveshaping. The distinctive character of its drive control and the level of control provided by the 1 pole VCF/tone circuit make it a highly sought-after module among sound designers and producers alike. The CDVCA module is an excellent addition to any modular setup and a must-have for anyone looking to push the boundaries of sound creation.

Example Usage

If you're new to using the Atovproject CDVCA, try patching an LFO or envelope generator into the 1V/oct input and then send an audio source into the input. Try adjusting the drive and filter controls while observing the output on an oscilloscope or spectrum analyzer to see how the PWM signal is being shaped and filtered. This will give you a good sense of the module's unique sound and how to use it creatively in your patches.

One possible usage example of the Atovproject CDVCA would be to use it as a sound shaping tool within a larger patch. Start by sending a complex waveform, such as one generated by a wavetable oscillator, into the CDVCA's input. Set the 1V/Oct input to track the same pitch as another element in the patch, such as a sequencer or MIDI controller. Use the drive control to add some grit and character to the sound. Finally, experiment with the filter/tone circuit to tame any harsh or unwanted frequencies. This can create a unique, highly customizable timbre that responds to your melodic input in real time.

Further Thoughts

The CDVCA module by Atovproject offers a world-first concept of a Class-D VCA with 1V/oct tracking, delivering an entirely new level of sound manipulation. Imagine scaling an ultrasonic PWM signal to the desired amplitude, then tracking it via the 1V/oct input. With frequency control, you get a crazy range of waveshaping that follows every note of your melody. The innovative clipping method in the drive control gives distortion with a unique character that doesn't depend on overdriving any circuitry. The module generates a simple square wave when there's no input, so it can also be used as a simple synth voice with VCO->VCA-VCF. With the Atovproject's CDVCA Eurorack module, the wild possibilities will inspire your musical creativity to new heights.
