TB DualVCF vs GSDSP Quantum Filter

Dual VCF - the ultimate dynamic filtering AUv3 plug-in! Dual VCF adds motion, shape, and colour. It produces evolving rhythmic movement and complex dynamic filter shapes. It contains dozens of analog filter models with that sought-after sound of the 70s, 80s and 90s. Combined with envelope followers and intuitive modulation editors, it provides almost infinite possibilities for creative aural exploration. Dual VCF features two filter sections, each supporting dozens of low-pass, high-pass and band-pass filter types. Every type is painstakenly modeled after analog filter types found in analog gear, analog synthesizers, and alike, including non-linear filter behavior. Dial in that characterstic 70s, 80s or 90s filter to add some analog flavor to your tracks! Each filter's cut-off frequency and resonance can be sequenced with an intuitive, free-running or beat-synced modulation editor. Seamlessly switch between sine, triangle, noise, or user-defined modulation waveforms. In addition, these parameters can also be modulated with the built-in envelope follower. The ToneBoosters DualVCF app captures the microphone (or external sound card) input and processes the signals in real time. To use it as a plug-in, use an AUv3-compatible host app such as Steinberg Cubasis, Apple Garageband, Audio Evolution Mobile Studio, Auria, AUM, or others. ToneBoosters DualVCF will appear in the list of Audio Unit extensions for effect plug-ins. How to use DualVCF as AUv3 plugin in a host program, start your favourite AUv3 host app (Steinberg Cubasis, Apple Garageband, Audio Evolution Mobile Studio, Auria, AUM, or others) and add TB DualVCF as Audio Unit insert effect to a track or output bus. See below on how to use Audio Units in various host apps. Key features: - The same professional sound as the acclaimed desktop version - Two analog filter sections with dozens of filter designs - Intuitive modulation editor for creative, rhythmic and evolving effects - Undo/redo, and A/B comparison - Color themes for the user interface - Max screen support in Garageband - Optimised for iPad and compatible with iPhone and iPod Touch What you should know: - Licenses acquired for this platform are not compatible with other platforms. - Audio Unit (AUv3) extensions require an iPad mini 2, iPad 4 or later models.

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).
