Oligarc Filter Standalone Analog Filter Plugin

  • Selectable filter shape: lowpass, wide bandpass, or narrow bandpass.

  • Large cutoff frequency control for expressive filter sweeps.

  • Resonance with self-oscillation at high settings.

  • Built-in soft-clipping brickwall limiter for output protection.

Oligarc Filter is a fully MIDI-controllable standalone filter plugin. At its core is the analog ladder filter model from Olga and Oligarc, including nonlinearity, instability, and musical character.

Choose from lowpass, wide bandpass, or narrow bandpass modes. Sweep the cutoff aggressively, push resonance into self-oscillation, and shape tone from subtle movement to unstable extremes.

A soft-clipping brickwall limiter is included to protect output levels when things get wild.
