CHIRP Voltage-Controlled Filter

CHIRP Voltage-Controlled Filter

 170,00 INCL. VAT

The Orphic Dynamics CHIRP VCF is a fully analog voltage-controlled filter that blends vintage-inspired design with modern versatility. At its core, CHIRP uses a modified Sallen-Key topology paired with a resonance feedback circuit reminiscent of the iconic Korg MS-20. This gives CHIRP its unique sound character, from smooth or grim tonal shaping to aggressive and chirping self-oscillation.

SKU: CHIRP Category: Tags: , , ,

CHIRP features three filter modes: Low-Pass (LPF), Band-Pass (BPF), and High-Pass (HPF), which can be used individually or blended for hybrid responses. With its crossfading capabilities, you can transition between filter modes, opening up a world of sound design possibilities.

The module’s high resonance levels push it into self-oscillation, turning the filter into a standalone sound source capable of producing melodic tones with CV or manual cutoff adjustment.

 

Controllable Parameters:

  • Cutoff (CV/Manual): Two CV inputs allow precise control over the filter frequency. Use one as an offset and the other for dynamic modulation from an LFO, envelope, or sequencer.
  • Resonance (CV/Manual): Adjust the resonance from warm and subtle to sharp, screaming self-oscillation.
  • Self-oscillation (CV/Manual): At maximum resonance, use CHIRP as a sine wave oscillator.
  • Mode Selection (CV/Manual): Choose LPF, BPF, or HPF, or blend between them for hybrid filter responses. The MODE CV Input provides voltage-controlled transitions across filter types for dynamic performance.
  • Crossfade Modes (CV/Manual): Gradually crossfade between filter modes.
  • Resonance Feedback Control: Switchable resonance feedback offers constant resonance or CV-based modulation.
  • Distortion: Built-in input drive adds subtle warmth or gritty distortion.
