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

At the end of a long day at the mixing desk, when everything has finally fallen into place, comes the best moment (just before pouring that glass of whisky): load an instance of NoLimits2 at the end of the processing chain, turn that big gain knob, lean back and enjoy. Its predecessor, NoLimits, was certainly a highly acclaimed limiting plugin already and did a very good job for many years, but NoLimits2 definitely takes it to another level. From ultraclean to tastefully saturated, NoLimits2 will make your mixes louder in style. NoLimits2 is a highend audio limiting plugin featuring: - a comprehensive set of 4 different limiting algorithms - all of them follow entirely different limiting strategies, giving you a choice of really unique sounds - from clean to nicely saturated, it’s all there - further control over attack, release and lookahead times allow for even more finetuning - up to 8x oversampling to keep all harmonics of the more colourful modes in check - stereo channel linking - state-of-the-art LUFS loudness metering, compliant to all the latest standards NoLimits2 is an AUv3 plugin which is compatible with all relevant hosts on iOS, like Logic, Garageband, Cubasis,... you name it.
