Quadra Envelope Generator - 12HP


The Intellijel ‘Quadra’ is a quad function envelope generator module. Each of the four channels can be used as an envelope or LFO. Each channel of the Quadra has three operational modes: Attack-Decay Envelope, Attack-Hold-Release Envelope, and Cycle AD envelope loops that repeat to become LFOS. Each function can have a linear or exponential curve and the Attack and Decay parameters have a very wide range allowing for times from 0.5ms to well over 30 seconds. 


  • 4 Independent Function/Envelope Generators
  • 3 Modes of Operation: AD (Attack-Decay), AHR (Attack-Hold-Release), Cycle (AD Envelope Loops)
  • Linear or Exponential Operation Selectable
  • Wide Time Range for Attack/Decay Controls: <0.5ms to well over 30s
  • All Analog and Discrete Logic for function generation (totally smooth and continuous waveforms)
