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.

Parameter Randomisation

Inject a burst of unpredictability with our dynamic parameter randomisation feature. Choose which parameters to affect and evolve your sound across three stages — gentle, medium, or fully random.
So whether you are searching for slight variations of a few parameters or you want to explore the full parameter space at random - we got you covered.

Modulation Built-In

Our modulation system lets you modulate any parameter with ease and precision, including individual depth control per parameter. Each modulator offers skew, sample & hold, and uni-/bipolar modes.

Choose from LFOs, Random Generators, custom-drawn LFOs, and a full suite of followers — from Amp and Pitch to advanced Spectral Followers like Brightness. Need more dimensions? Explore 2D modulators such as 2D LFO, 2D Random, Strange Attractors, and the Double Pendulum for truly chaotic motion. On iOS, 3D Motion lets you control parameters via the device’s gyroscope and accelerometer.

And if that’s not enough, you can dive into the world of Cross Modulation by expanding the system even further — using modulators to modulate the parameters of other modulators. Sounds complicated? It’s not! The concept is simple, but the possibilities are endless!
