Stereo Delay / Echo meets next-level Modulation

Picture this: A classic stereo delay with feedback, a vintage treasure for the ages, now fused with the most transcendent, mind-bending modulation system you’ve ever encountered!

Delay: Dive into the heart of time manipulation using either the retro Tape mode or the modern super-clean Fade mode. Seamlessly toggle between BPM synchronization, even 5-tuplets, or use any time in ms. Use the Fine control for pushing / dragging micro-timings or modulate your delay lines like never before.

Filter: Nested within the feedback path, switchable lowpass, highpass, and bandpass filters empower you to beautifully sculpt your echos. Easily add modulation for unique dynamic movement and depth.

Feedback: Define the intensity in conventional percent or our modern dB/s approach. Use crossfeed for classic ping pong delay style effects. Increase the intensity by using the over-feedback mode to build up your echos beyond infinity.

Each section can be toggled between stereo and dual mono for even more interesting stereo effects and control. Use our parameter randomisation feature to explore the plugin’s sound at random. And if that’s not enough use our next-level modulation system to modulate pretty much everything using LFOs & Random Generators (also in 2D!), Envelope Followers, Macros and even dynamic chaotic systems.

Parameter Randomisation

Inject a burst of unpredictability with our dynamic parameter randomisation feature. Evolve your sound in three stages - gentle change, medium change, and fully random. Choose which parameters to transform, and save these unpredictable sonic journeys in presets for endless inspiration.
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.

Built-In Modulation

Our revolutionary modulation system, seamlessly integrated for your convenience. It offers simplicity in operation, allowing you to effortlessly modulate any parameter with precision. With the flexibility to customize modulation depth individually for each parameter you have complete control over your desired effects. Each modulator offers a skewable amount, sample and hold, and unipolar/bipolar functionality.
Unleash your creativity with an array of built-in generators, including LFOs, Random Generators, and even a custom LFO that empowers you to draw your own unique shapes. Additionally, our comprehensive collection of followers, such as Amp Follower, Pitch Follower, and advanced Spectral Followers like Spectral Brightness, enable dynamic and responsive modulation like never before. 1 dimension is not enough? We added 2D modulators like 2D LFO, 2D Random, 2D Strange Attractors and 2D Double Pendulum so you can even use chaotic dynamic systems as a modulation source.
Also now available on iOS: 3D Motion lets you control parameters using the gyroscope / accelerometer!
