Key Features
The Intellijel Quadra Expander is a expander module for the Intellijel Quadra Module. Its features enhance the core functions of the Intellijel Quadra with four EOC (end of cycle) pulse outputs that correspond with the four function generators on the Quadra, and a special Quadrature mode for envelopes 1+2 and 3+4. The Quadra Expander essentially adds voltage control to the function generators of the Quadra. The Expander is a perfect companion to the Quadra module and when paired can produce complex evolving rhythms.

The top two functions and bottom two functions are paired in two separate ways. The first being Quadrature mode and the second being the OR outputs at the bottom. Quadrature mode means you don't need a trigger input because the two functions (1+2) trigger each other. Quadrature mode links the function generators into pairs of looping envelopes that are interdependent. What Quadrature mode does is that it creates an interdependancy between the paired function generators where their attack and decay times determine each others timing and re-triggering, perfect for creating out of phase modulating which can produce complex results.
The Quadra Expander conveniently features yellow LEDs that indicate when the respective function generator has reached the End of Cycle. To the right of each EOC output are two mini knobs that allow you to modulate the attack and decay time from the Quadra which is handy for creating complex evolving rhythms.
