Intellijel designs - Quadrax

Quadrax is Intellijel's answer to all function generator needs in a quadruple format. Bursts, LFOs, and everything is voltage-controlled.

Quadrax packs four voltage-controlled AD envelopes in a slim 14HP module. You can blend the envelope behavior between exponential, linear, and logarithmic. This blending is also controllable via CV, as Quadrax comes with a powerful modulation matrix on board.

There are 4 CV inputs that can be freely assigned to each channel. Each channel offers the parameters Rise, Fall, Shape, and Level. Additionally, it's easy to adjust the modulation intensity using the internal attenuverters (both positive and negative). As you can imagine, the possibilities here are vast, ranging from simple envelope-to-filter-cutoff actions to complex generative cross-modulations.

Quadrax has a total of 5 modes: AD, AHD, Loop, Burst, and LFO. The LFO is the bipolar version of the looping AD envelope and can be morphed in shape. Furthermore, the LFO can also run freely without any trigger input! Intellijel provides you with everything you need to set your Eurorack system in motion. It is also possible to link channels together and trigger them mutually. Each channel can be triggered by the one above it (Channel 1 by Channel 4), and you can choose between the same trigger, end-of-rise, or end-of-fall.

The Qx Expander additionally provides you with the EOR and EOF triggers directly at your disposal.
