Intellijel Quadra And Expander Tutorial

Published on Aug 3, 2017

"The Intellijel Quadra and Expander modules comprise four parallel function generators (more commonly referred to as 'Envelope Generators'. The Quadra function generators have three modes, AD (Attack, Decay), ASR (Attack, Sustain, Release) and Cycle (perpetually repeating AR envelope or unipolar LFO). Each function can be configured to have a linear or exponential curve and they feature a wide time base control from 0.5ms, to over 30 seconds. The Expander enhances the core functionality by allowing attenuated voltage control over Attack and Decay for each function generator, a Quadrature mode, and an analog OR mixer for each function generator pair.

This video will cover both the Quadra and its optional Expander module.

Quadra Features:
Four function generators with Attack and Decay times ranging from from 0.5 milliseconds to over 30 seconds.
Three modes: AD (attack, decay), ASR (attack, sustain, release), Cycle (AD envelope loops)
Exponential and Linear envelope curves

Additional Expander Features
Four End of Cycle pulse outputs corresponding to the four function generators.
Voltage control of attack and decay (with attenuators) of all four envelopes
Two analog OR (Also known as Peak Circuit) logic outputs that are normalled to the two pairs of envelopes with attenuators.
Special Quadrature modes"
