Random Source Serge New Gates VCFX

The Serge New Gates / VCFX from Random Source offers a combined toolset for managing timbre and amplitude for a single voice, giving you a highly versatile VCA beside a voltage controlled band pass and low pass filter. On the left side, a uniquely capable VCA provides multiple modes for processing incoming voltages, with mode set by the three position switch. Intended for processing audio signals, each jack marked with a black ring is AC-coupled, rejecting DC signals like CV in favor of optimized processing of audio. In DC mode, the Gain control sets a base level for the signal, which is then controlled by the CV signal present at the Linear input. In AC mode, the signal is controlled by the Logarithmic input, producing more organic response. Finally, the Mod input allows you to ring modulate the input signal with another audio source. Despite the mode settings leaning into one or another processing technique, each modal input can be used simultaneously, enabling you to derive more complex results as control inputs work together to affect the output signal.

On the right side of the module, a recent Serge design from 2023 offers a voltage controlled band pass filter with a low pass output. The Gain control sets the level of the signal as it passes into the filter, while manual and CV controls for both resonance and filter frequency can be used to shape the tone of the filter. Each CV input has an attenuverter inline, allowing for precise targeting of sweet spots to tease out unique and ear-catching spectral transformations. Naturally, the Gate and VCFX sides can be used independently in a patch, though combined they offer a streamlined toolset for creating a vast range of timbres from a single oscillator voice. Adding multiple flavors of harmonic enrichment with the Gate and filter input stage, then sculpting tones with the VCFX is a powerful pathway for creating complex and evolving tones in a patch. Whether you are designing your first modular voice or looking for new flavors for your monster system, the Serge New Gates / VCFX 2023 from Random Source is a formidable platform for timbral exploration in a convenient package.
