Heretic Polivoks VCF / VCA Utility Module

Tembra Heretic

Sculpt the timbre of your patches with Heretic from Tembra, a compact polivoks topology VCF and VCA with a lowpass / bandpass crossfader, overdrive, and sub-oscillator. The trimpots offer extensive control over the filter section, allowing for manual control over cutoff, resonance, and the crossfade between the filters, along with corresponding CV jacks and attenuverters for each parameter. The engageable VCA mode provides an additional layer of processing to your signal, allowing you to easily add dynamic depth to your patches. Fuse aggression into your sound with the optional drive circuit, applying edgy saturation to any audio you pass through it. Apply weight to your signal with the onboard sub-oscillator section, which analyzes your incoming audio and adds a sub-octave square wave underneath the signal; blend this oscillator into your sound using the dedicated mix knob and octave control button. If your Eurorack system is in need of a compact yet powerful utility module, completely transform the timbre of your patches with Heretic from Tembra.
