Intellijel Multigrain: A Deep Dive into Modulation Possibilities

Intellijel’s Multigrain module steps into the spotlight as a modulation powerhouse for Eurorack enthusiasts, and in this official video manual, the Canadian brand delivers a thorough exploration of its modulation architecture under firmware 1.2. With a focus on assignable CV inputs, randomisation, and creative routing, the presentation is classic Intellijel: practical, patch-centric, and brimming with workflow tips. Whether you’re after evolving textures, granular chaos, or tightly controlled pitch sequences, Multigrain’s modulation matrix is shown to be both flexible and inviting. This article unpacks the video’s key demonstrations, highlighting how Multigrain can become the modulation nerve centre of a modern modular system.

Meet Multigrain: Modulation Hub for the Modern Modularist

The video opens with a focused introduction to the Multigrain module, positioning it as a central modulation tool for complex Eurorack patches. Intellijel’s approach is methodical, mapping out the available modulation options right from the start. The module’s front panel is laid out with clarity, revealing a suite of assignable inputs, randomisation controls, and outputs designed to interface with the wider modular ecosystem.

From the outset, it’s clear that Multigrain isn’t just about granular synthesis—it’s about modulation as a creative force. The demonstration hints at patches that use modulation in a variety of ways, suggesting that this module is intended to be the beating heart of evolving, animated soundscapes. As is typical for Intellijel’s presentations, the emphasis is on practical signal flow and real-world patching rather than abstract theory.


Assignable Inputs, Randomness, and Routing: The Core Features

Multigrain’s three assignable CV inputs—X, Y, and Z—form the backbone of its modulation matrix. Each input can be routed to any parameter, with individual depth and polarity settings, making it possible to sculpt intricate modulations per scene. The video walks through the process of assigning modulation, demonstrating how the mod pages allow for quick and intuitive mapping. Attenuverter controls and visual feedback via LEDs ensure you know exactly how your CV is being applied.

Random modulation is given equal weight, with a dedicated RAND page offering per-parameter randomness that can be positive or negative in depth. The inclusion of two assignable modulation outputs, A and B, rounds out the feature set, enabling users to route modulation signals out to other modules or even back into Multigrain itself. This flexibility is a nod to Intellijel’s modular philosophy—everything is patchable, and nothing is locked in.

Multi-grain generates its own random modulation per parameter that we can apply to our sounds in exactly the same way as X, Y and Z.

Layered Sound Design and Morphing: Modulation in Action

Modulation is applied per scene, allowing you to morph between different modulation assignments across all sounds.

The video dives into practical sound design, showing how modulation can be assigned to different parameters across scenes for evolving textures. By patching sources like the FSR 1U or Tangrams into the X or Y inputs, users can modulate pitch, tone, size, and more, with each scene holding its own unique modulation assignments. This per-scene approach means you can morph between entirely different modulation setups, opening the door to dynamic transitions and animated sonic landscapes.

Morphing itself is a highlight, with the morph fader serving as both a manual and CV-controllable macro. By patching an LFO from Dixie into the morph input, the video demonstrates automated movement between scenes, with the morph fader’s LED providing real-time visual feedback. The ability to automate or perform scene morphs adds a performative dimension to Multigrain’s modulation capabilities.

The editorial takeaway is that Multigrain’s modulation system isn’t just about tweaking parameters—it’s about orchestrating movement and evolution across your patch. The module encourages experimentation, letting users layer modulations and morph between them for rich, ever-changing results.

Creative Modulation Techniques: Quantising, Looping, and More

Intellijel showcases a range of modulation tricks that push Multigrain beyond the basics. Quantised random modulation is a standout, allowing users to apply random pitch modulation and then lock it to musical intervals via the built-in quantizer. This makes it easy to generate melodic sequences that are both unpredictable and harmonically grounded—a boon for generative and experimental patches.

Looping and freeze functions add further depth, with the ability to modulate the looping recorder’s freeze state from any modulation source. The video demonstrates how to assign gates or CV to freeze, enabling stuttered or time-locked effects. These techniques are presented as tools for creative workflow, encouraging users to think beyond static modulation and embrace evolving, interactive control.

A lot of the fun comes from experimenting with random modulation parameters, and we've done our best to match different types of random…

Managing Modulation: Assignments, Outputs, and System Integration

The latter part of the video is packed with practical advice for managing complex modulation setups. Intellijel details how to apply modulation assignments across multiple scenes and sounds, using modifier buttons to quickly propagate settings. There’s a clear focus on efficiency—features like randomising modulation assignments and clearing them en masse are designed to keep patching fluid and flexible.

The two modulation outputs, A and B, are explored in depth, with seven selectable output types ranging from morph fader CV to grain triggers and envelope followers. These outputs can be routed to external modules or fed back into Multigrain, making the module a true modulation hub. The presentation closes by emphasising Multigrain’s role as a central node in larger modular systems, capable of both generating and distributing complex modulation patterns with ease.
