VintageRack is a minimalistic and convenient multi-effect application that contains modules realistically modeling notable retro gear from the early digital era with their inherent aesthetics and atmosphere. Most of the effects in this application have been inspired and based on the principles of actual hardware from the 70s and 80s, which is great for giving the sound of any instrument the nostalgic and emotional mood of old recordings. This application has a clean and intuitive user interface with a well-considered structure. The signal path is split into seven slots: the first for input control, the last for output, and five customizable effect modules in between. Each module features a master fader for adjusting effect presence and a mute button for smooth toggling. These parameters can be easily assigned to MIDI controls right from the main screen, improving both workflow and productivity. Smooth transitions between presets and on-screen pads for quickly switching presets that can be easily assigned to MIDI controls allow flexible effect selection during live performances or studio recordings. Another great feature of VintageRack is the ability to set a lower bit depth of processed signal, typical for early digital devices, both for the entire path and for individual modules. As with these devices, this application models pre- and post-processing of the analog signal both before and after the digital circuits with the addition of companders, emphasis and filters, which makes the sound similar to the real devices. Effect modules: - Analog modeled compressor. - Three band equalizer typical for mixing consoles. - Classic and reverse delays with modulation feature. - Two Chorus modules are precise emulations of known devices. - Two modules of Flanger with different options and tones. - Two modules of Phaser with various sound character. - Filter module controlled by LFO or envelope generator. - Faithful emulation of classic Wah effects with added automation. - Combined effect of Tremolo and Vibrato with separate rate. - Ring modulator with additional modulation of carrier. - Three types of Fuzz with modulated filters. - Emulation of one of the early digital reverbs. - Vintage exciter with bass enhancer. - Spring reverb with tube preamp. - Advanced formant filter with voice synth mode. - Input slot contains Noise gate and Automatic gain control. - Output slot contains tape-style saturation and three types of tonestacks. VintageRack is a universal application for iOS and macOS. It can work on iPhone and iPad as well as Mac / MacBook with M1 chip (and later). VintageRack works on iPhone and iPad standalone, as an Audio Unit or Inter-App Audio module, and supports Audiobus and Ableton Link. On MacOS, VintageRack can works both as a standalone application and as an Audio unit (AUv3) with DAWs and other hosts that support AUv3 plugins. All application features are available on iOS and macOS, including MIDI support (with a MIDI learn option) and audio unit parameters. VintageRack has a built-in detailed description of all parameters also available as PDF file on the application site.

About

GSDSP Quantum Distortion

Explore four distinct distortion effects—Saturation, BitCrush, Ring Modulation, and Downsampling—blended and controlled via an intuitive XY pad. Shape harmonics, reduce digital resolution, introduce inharmonic motion, and create classic digital degradation for unique audio textures.

Highlights
  • Four distortion algorithms (Saturation, BitCrush, Ring Modulation, Downsampling)
  • Intuitive XY pad for blending effects
  • Custom waveshaping saturation
  • BitWarp for tonal variation
  • Tunable oscillator for ring modulation
  • Adjustable downsampling rate and jitter
  • AUv3 audio effect plugin

Four complementary distortion algorithms — Saturation, BitCrush, Ring Modulation, and Downsampling — blended and shaped through an intuitive XY pad. Saturation Shape harmonics using Quantum Distortion’s custom waveshaping saturation. Adjust Drive to set the intensity from subtle warmth to strong coloration, and use Asymmetry to introduce controlled even-harmonic emphasis of vintage tube characteristics. BitCrush Reduce digital resolution using BitCrush and reshape the crushed signal with BitWarp, which bends the quantization curve for additional tonal variation. This combination allows precise control over both the amount of reduction and the character of the resulting digital artifacts. Ring Modulation Introduce inharmonic motion using ring modulation, generated by multiplying the input with a tunable oscillator. Adjust frequency and amount in real time to create anything from light metallic shading to dense, shifting sidebands. Downsampling Lower the sample rate using Downsampling, reducing temporal resolution for classic digital degradation effects. Set the rate down to 200 Hz or introduce Jitter for controlled randomness, adding instability and movement to the downsampled signal. XY Pad Blending Navigate between the four distortion algorithms using the XY pad, allowing smooth transitions or static blends across the processing modes. The background updates to reflect the current region, providing clear visual feedback while exploring hybrid distortion shapes and interactions. Quantum Distortion 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).
