Description
Step into a world of sonic exploration with the Intellijel Quadrax, a 4-channel multifunction Eurorack module that redefines modulation possibilities. Whether you're crafting ambient soundscapes or chaotic noise, Quadrax offers a toolkit tailored for every sound architect. Each channel of this versatile module boasts five distinct modes: Attack/Decay, Attack/Hold/Release, cycling envelope, pulse burst, and a morphable LFO. This allows you to seamlessly shape and control your sound with precision.
With its extensive CV input capabilities, the Quadrax opens a universe of patching possibilities, letting you manipulate attack and decay parameters and create complex, evolving envelopes. Need more dynamism? Link multiple channels to design intricate, multi-stage envelope curves that push the boundaries of traditional sound design.
For those who thrive on customization, the module offers adjustable characteristic curves from logarithmic to linear to exponential per channel, ensuring that every modulation is as unique as the artist themselves. Expand your creative horizons by pairing it with the Intellijel Qx module (sold separately), and watch your modular setup transform into an unparalleled powerhouse of sonic potential.
Key Features:
- 4-channel function and envelope generator
- Five modes per channel: AD, AHR, cycle, pulse burst, morphing LFO
- CV inputs for attack/decay control per channel
- Channels can be chained for complex envelope creation
- Adjustable characteristic curve: logarithmic to linear to exponential
- Trigger input and output per channel
- Compatible with Intellijel Qx module for expansion
- Current consumption: 106mA (+12V) / 9mA (-12V)
- Width: 14 HP; Depth: 38 mm

Features and functionality
-
Quadrax can function as a quad wavetable VCO, offering a complex VCO, envelope, and LFO with attenuation/modulation control via four CV inputs.
Source -
Quadrax's assignable CV matrix and various channel chain modes make it ideal for generative music, offering a different approach than Maths.
Source -
The CV modulation assignment on Quadrax involves a three-step process using labeled buttons and LEDs to indicate assignments and attenuation levels for each channel.
Source
Comparisons
-
Maths is preferred in larger setups for its flexibility and unique CV/analog functions, while Quadrax is favored in smaller systems for efficient space use.
Source -
Unlike Maths, Quadrax offers random modes and bursts, which are particularly advantageous for those focusing on generative ambient music.
Source -
Compared to the mod matrix on the MicroFreak, some users find Quadrax's CV assignment process quicker once familiar with the order of operations.
Source
User experience
-
Quadrax's user interface is praised for its clarity; users can quickly dial in settings without frequent manual reference, unlike Maths' glyph-based UI.
Source -
Users appreciate Quadrax's straightforward interface, though some find the small button legends challenging, suggesting Intellijel should include a cheat sheet next to the manual.
Source -
Some users find the Quadrax CV assignment process challenging and often revisit Intellijel's tutorial videos for clarity, highlighting the potential complexity of its interface.
Source
Use cases and applications
-
A combination of Quadrax and 3X MIA is recommended for setups prioritizing traditional envelopes and LFOs, matching Maths' functionality in the same HP space.
Source -
Quadrax is praised for its performance in ambient setups due to its multiple channels, random modes, and morphable complex LFO shapes, making it suitable for intricate soundscapes.
Source -
Users seeking practical application examples for Quadrax often express a need for deeper tutorials beyond the manual's basic functionality descriptions.
