Understated but full of capabilities this module pairs a low pass filter and VCA together with continuously variable distortion. The non-linear transfer function allows the filter to achieve stable self oscillation, or dialled back to linear for clean and stable digital filtering. Pioneering zoom controls allow frequencies from ultrasonics down to extremely slow CVs to be set quickly and precisely, while providing all modulating inputs with a bipolar gain or attenuation. Audio demos of the module recorded off the output without any processing:
- Resonant filter, square wave input, wobble LFO and manual sweeping of cutoff
- Self resonating FM, cutoff driven from external oscillator at audio frequencies
- Self FM resonating, LFO to VCA, peaky LFO on cutoff and manual depth of FM input feedback from output
