CubuSynth - Dual CS-20 VCF

Product information "CubuSynth - Dual CS-20 VCF"
The CubuSynth Dual CS-20 VCF is a versatile module that combines two 12db filter cores in a dual/stereo configuration. It is inspired by the iconic Korg MS-20 synthesizer, offering similar sound characteristics while the resonance can be pushed even further.

The module provides multiple filter modes, including low pass and high pass, which can be blended together to create a diverse range of filter responses. This allows you to shape your audio signal in various ways, from smooth and warm low pass filtering to more aggressive high pass filtering.

One of the standout features of the CS-20 VCF is its self-oscillating resonance capability. When the resonance is turned up, the filter produces a sine wave that can be used as an additional sound source. This feature adds to the versatility of the module, allowing you to create complex and evolving sounds and even cross-FM modulation possibilities.

The frequency and resonance parameters can be controlled via control voltage (CV) inputs. The frequency CV input can be attenuverted, meaning it can both attenuate and invert the incoming CV signal. This gives you precise control over the modulation depth and direction for frequency modulation.

The resonance CV input includes an attenuator, allowing you to adjust the modulation depth for the resonance parameter. This feature gives you the flexibility to add dynamic and expressive modulation to your sounds.

Additionally, the CS-20 VCF provides a 1V/Oct input, which allows you to control the filter's frequency using a standard 1V/Oct control voltage. This input is stable over a range of at least 2 to 3 octaves, ensuring melodic tracking and integration with other modular synthesizer components.

Overall, the CubuSynth Dual CS-20 VCF offers a powerful and flexible filtering solution with intuitive routing and modulation options. It is designed to inspire creativity and provide a wide range of sonic possibilities for your modular synthesizer setup.

Manufacturer "CubuSynth"
Cubusynth was founded by Ruben Sponar in 2020 and is located in the south of Portugal. We create Eurorack Modules, a modular synthesizer format. Modular synthesizers, unlike pre-wired synthesizers, have panel-mounted audio, control, and sync jacks that allow direct connections (via patch cords) from any module to another module. The result is an endless universe of possibilities and combinations to achieve new sounds. At CubuSynth we give you 3 ordering options, we provide modules assembled, calibrated and ready-to-use. The DIY (do it yourself) version of the modules, with all the components needed for assembly, as well as the respective instruction manual, this option is aimed at electronic soldering enthusiasts who like to get their hands dirty and see the magic of electronic connections come to life through your own hands. We also offer the possibility of purchasing the PCB and the front panel so that anyone with the necessary experience and knowledge in electronic soldering and modular synthesis can assemble our modules with the components they like best, in order to give our customers some freedom to create and customize our modules.
