GSDSP Quantum Filter
iOS Universel / Musique
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).

Quoi de neuf dans la dernière version ?
- New: Modulation Range Info now displays a text representation of the applied modulation range (current / min / max)
- Magic Series: The active curve in the Curve Editor can now be randomized (add random points and/or move existing ones)
- Fixed an issue when switching presets via MIDI Program Change messages (Thanks Maxim)
- Fixed the LFO "Round" wavetable
