Filterbank

Filterbank is a dual-filter plugin with advanced analog modelling, bringing the warmth and character of legendary analog hardware filters into a precision-engineered digital environment. It features a State Variable Filter architecture with non-linear feedback paths, capacitor simulation, and component interaction modelling for authentic analog sound. Two independent filters with lowpass, bandpass, and highpass modes can be arranged in parallel or serial configurations.

A comprehensive modulation system with LFO, ADSR, and AR envelopes — triggered by audio, sidechain, or MIDI — delivers evolving, dynamic control over all filter parameters. Multi-stage distortion, thermal drift simulation, precision pitch tracking, and 4x oversampling complete a creative powerhouse for producers, sound designers, and performers.

Features

• Dual SVF Filter System: Two independent State Variable Filters with lowpass, bandpass, and highpass modes, Moog-inspired resonance feedback, and precise blending via LBH and BLH correction controls. Filters can be routed in parallel, serial, or anywhere in between for maximum sonic flexibility.
• Multi-Stage Analog Distortion: Four distortion modes (Clean, Warm, Crunch, Edge) with asymmetric processing, DC offset management, and dynamic component saturation deliver everything from subtle analog warmth to aggressive harmonic destruction.
• Comprehensive Modulation System: LFO with sine and sawtooth waveforms (including DAW-synced tempo divisions), full ADSR envelope, AR amplitude envelope, and envelope follower mode. Multiple trigger sources — audio threshold, sidechain input, and MIDI — enable evolving filter sweeps, rhythmic gating, and live performance control.
• Harmonic Interval Locking: A 12-position Harmonics switch locks Filter 2 to musical intervals relative to Filter 1, creating harmonically related dual-filter textures. Free mode allows fully independent control.
• Thermal Drift & Console Noise: THD drift simulation recreates the organic "breathing" quality of analog circuits, while calibrated pink noise adds authentic texture and character to the signal path.
• Precision Pitch Tracking: Dynamically adjusts filter frequencies based on input pitch detection, creating musical filter responses that follow the source material — with dedicated modes for standard and bass-focused tracking.
• Full MIDI Integration: Dedicated MIDI note mapping for triggering, gating, blocking, and unblocking both AR and ADSR envelopes, enabling precise sequenced modulation and live performance control.
• 4x Oversampling: Toggleable oversampling with anti-aliasing significantly reduces artifacts at high resonance settings and upper-frequency content for pristine audio quality.
