Intellijel Swells 3U: creative and modulable Eurorack reverb module

Intellijel Swells 3U is a stereo reverb module for Eurorack designed to offer an extremely wide range of sound spaces, from realistic environments to fully experimental textures. Thanks to its 9 reverb algorithms, you can go from classic halls and plates to vintage digital environments and abstract, deeply evocative soundscapes.

Designed for those who love to explore and shape sound, Swells combines professional audio quality with advanced modulation and signal manipulation tools.

SWELL generator: dynamic and expressive modulation

The creative heart of the module is the SWELL Generator, an advanced multi-mode envelope follower that generates dynamic modulations based on the input, output or sidechain signal. With Rise, Fall and Threshold controls, you can sculpt the evolution of reverb organically and musically.

The dedicated SWELL CV output also allows you to control other modules, turning Swells into a true modulation source within the Eurorack system.

Total control and advanced modulation

Every reverb parameter can be modulated via the 9 CV inputs with attenuverter, allowing complete and precise control. Controls include pre-delay, size, decay, damping and EQ, as well as unique EBB and FLOW parameters specific to each algorithm.

Creative functions for advanced sound design

Swells integrates a number of tools designed to expand creative possibilities:

FREEZE captures and holds an audio fragment to create endless drones and textures. REVERSE reverses the signal for unique temporal effects, while BURST introduces energy via noise or feedback. LO-FI mode adds character by degrading the signal in a controlled manner.

These functions can be assigned and triggered externally, making the module extremely performative.

Professional audio quality and Eurorack integration

With 96kHz/24-bit audio conversion and 32-bit floating point internal processing, Swells ensures high and detailed sound quality. The module also supports send/return modes for seamless integration into complex setups.

Compact and powerful, it is an ideal tool for producers, sound designers and modular musicians looking for creative and highly modulable reverb.
