Analog warmth meets flexible routing and dynamic modulation in a filter workstation built for creative sound design. Analog-Modelled Filters Quantum Filter uses resonant, analog-modelled filter designs that behave smoothly and musically across the entire spectrum. With no cramping, stepping, or digital artefacts, the filters remain stable even under rapid modulation. At high resonance settings they can reach self-oscillation, similar to classic hardware circuits. Filter Types & Routing Choose from 11 filter modes, including Lowpass, Highpass, Bandpass, Notch, Shelving options, Bell, and Ladder Lowpass in 1–4 pole configurations. Combine filters in series (up to three stages) or parallel (up to two), resulting in over 2,000 possible routing combinations for detailed tone shaping and complex layered filtering. Built for Modulation Designed to handle fast, artefact-free modulation, Quantum Filter responds cleanly even under rapid parameter changes. Its stability makes it suitable for dynamic environments, rhythmic modulation, or complex movement across multiple filter stages. Stereo and Dual Mono Switch between stereo and dual mono modes to shape the stereo image. In dual mono mode, left and right channels can move independently, enabling asymmetric movement, wider imaging, or separate modulation paths for each side. MIDI Control Quantum Filter integrates ADSR & AR modulators that respond directly to MIDI, allowing envelope-driven filter motion that behaves like a synthesizer’s filter section. This integration adds expressive control for rhythmic gating, animated sweeps, and dynamic shaping based on your playing or sequencing. Quantum Filter is an AUv3 audio effect plugin compatible with Logic Pro, AUM, Cubasis, GarageBand and many more. A Desktop version is also available for Windows and macOS (VST3 / AU / AAX).

Quarked

Features
Read full description

Quarked is a high-performance granular synthesizer designed for precision sound design. Built around a native C-based audio engine, it prioritizes low-latency manipulation and a functional workflow that stays out of your way. Capture audio directly via the integrated tape-style recorder or import existing samples to begin deconstructing them. Quarked treats sound as a physical material, allowing you to zoom, slice, and re-texture with tactile, high-precision controls. The Engine: Granular Core: Independent control over grain size, density, position, and scan speed. Performance First: A native audio backend ensures smooth parameter interpolation without artifacts. Note-Level ADSR: Professional-grade envelope shaping with exponential curves for natural release. The Workflow Precision Ruler: Navigate waveforms with high-resolution sliders designed for micro-adjustments. Technical Aesthetic: A flat, distraction-free interface inspired by modern studio hardware. Dynamic FX Chain: A reorderable signal path featuring Delay, Reverb, Shimmer, and a 3-band technical EQ.
