About

GSDSP Quantum Delay

This app offers a vintage-inspired stereo delay effect with advanced modulation, flexible filtering, and precise timing controls. It allows users to sculpt unique echo textures, from warm analog sounds to complex, evolving soundscapes.

Highlights
  • Vintage-inspired stereo delay
  • Deep modulation system
  • Flexible filtering (LPF, HPF, BPF)
  • Precise timing controls (BPM, ms)
  • Switchable stereo/dual mono modes
  • Advanced modulation sources (LFO, Random, Envelope)

Read full description

A vintage-inspired delay supercharged with deep modulation, flexible filtering, and creative timing that pushes echoes into new dimensions. Classic Delay, Reinvented Quantum Delay takes the charm of a vintage stereo delay and fuses it with our next-level modulation system. Switch between the warm character of Tape mode and the pristine clarity of Fade mode, lock to BPM (including 5-tuplets) or dial in precise times in milliseconds. Use the Fine control for subtle push-and-pull micro-timing — or modulate your delay lines in ways traditional delays could only dream of. Sculpted Echoes Shape your repeats with switchable lowpass, highpass, and bandpass filters placed directly in the feedback path. Add modulation to create evolving tones, gentle movement, or drifting, frequency-shifting echoes. From warm analog-style rolls to shimmering, swirling textures, it’s all there. Feedback with Precision Control your delay tail behavior using either traditional % feedback or our modern dB-per-second decay system — ideal for predictable, musical decay even when the feedback path becomes complex. Enable Crossfeed for classic ping-pong stereo bounce, or push into Over-Feedback to create dense, self-building echoes that drift toward infinity. Stereo or Dual Mono Every section of Quantum Delay — delay, filter, and feedback — can switch between stereo and dual mono modes. Create tight, controlled stereo images or break them apart for wide, offset, unpredictable spaces. Dual mono modulation unlocks complex stereo interplay and beautifully asymmetric echoes. Modulation Without Limits Quantum Delay integrates our advanced modulation system, letting you modulate nearly anything: delay time, filters, feedback parameters, stereo controls, and more. Use LFOs, Random Generators, 2D modulators, Envelope Followers, Macros, and even chaotic systems to push your echoes far beyond traditional delay behavior. Or use our parameter randomisation feature to explore the plugin’s sound at random. Quantum Delay 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). More information here: https://gs-dsp.com/products

About

Secta

This audio effect dynamically splits incoming sound into two distinct processing paths, allowing for independent sculpting of each layer. It shapes accents, amplifies details, and guides each sonic dimension for unique timbral results. Designed for sound designers and musicians seeking unconventional audio manipulation.

Highlights
  • Dynamic audio splitting
  • Independent effect processing per layer
  • Amplitude threshold control
  • Envelope shaping
  • Customizable sonic dimensions
  • Colorizer with no mix parameters
  • AUv3 extension compatibility

Secta is an audio effect that dynamically splits incoming audio in two sections and processes each with an exclusive kit of effects, sculpting silence, shaping accents and amplifying hidden details, guiding each layer into a parallel sonic dimension.  A sound-designer (unforeseen) dream. Secta is part of totem/ series by K-Devices: unconventional audio effects coming in a compact format, easy to use, at a lower, convenient price. Building on the concept of a multidimensional gate, Secta processes the audio in a unique way, adding an ephemeral and dramatic touch to acoustic instruments, warmly disintegrating loops, injecting abrupt drops and re-texturizing your lines, or throwing down any beat into a dark path of fragmentation. Hard-to-describe with classic effect categories, Secta processes both sides of a gated source independently, acting as a counterpoint amplitude sculptor.
  Secta cuts to (re)generate.  Secta is a colorizer, no mix parameters are available: just load Secta onto your track and let it inspire you with its timbrical shades.  A gate, a dynamic multi-distortion, a double headed tectonic monster, a trembling detuned textures generator, and more… so many uses of Secta have yet to be discovered! HOW IT WORKS At first, Secta splits the incoming signal acting as a gate effect: the user sets an amplitude threshold using the Verge and Boost parameters. The signal’s amplitude portion greater than the threshold value generates an envelope which controls the Above and Below sections. The envelope itself controls the frequency of a lowpass filter in the Above section (resulting similar to a lowpass gate), while its inverse value controls the amplitude of the Below section. Such envelope can be shaped using several global parameters: Smooth, Retain, and S/C. Above and Below sections process sounds using a different set of effects each: the more rumbling Above, the more textural and looney Below. Using one section at a time holds interesting sculpting results, while combining and balancing them is great for creating richer textures. SHAPE THE ENVELOPE /// Set Verge and Boost to create the envelope that will control Above and Below; use Smooth and Mode to shape it in different ways. 2 WORLDS /// Above and Below, two sides of the same sound, individual paths (different effects and moods), which eventually converge in a new sonic entity. SCULPT /// Above and Below sections come with Drive and Lo/Hi pass filter the get the perfect shape for any sound project. MANDATORY PROCESS /// No dry/wet here: embrace the totem wisdom and get processed! LOCK PARAMETERS /// Enable lock toggle to preserve key parameters values while browsing presets. IN-GUI INFOS /// Enable Infos toggle to get all parameters details always in sight; just tap on a parameter. 2 FLAVOURS /// Dark and light skin. *** Please note: Secta is an Audio Unit extension (AUv3) – it only works in an AUv3 host app like AUM, Logic, Drambo, Cubasis, etc... ***
