Behringer 1033 Dual Envelope Generator Module, $69!

The Behringer System 100 1033 Dual Envelope Generator is a Eurorack module inspired by the classic Roland System 100M. This module provides two independent envelope generators, each with its own set of controls for Attack, Decay, Sustain, and Release (ADSR). The 1033 module is designed to offer precise control over the dynamics of your modular synthesizer system, making it an essential tool for shaping and modulating sounds.

Key Features:

Dual Envelope Generators:

  • Two Independent Envelopes: Each of the two envelope generators can be used independently, allowing for versatile modulation options within your modular setup.
  • ADSR Controls: Each envelope generator features four controls (Attack, Decay, Sustain, Release) for shaping the envelope of the signal. These parameters control the onset, decline, sustain level, and release time of the envelope.

Control and Modulation:

  • Manual Gate Buttons: Each envelope has a manual gate button, allowing you to trigger the envelope manually for testing or performance purposes.
  • Gate and Trigger Inputs: Each envelope has both gate and trigger inputs, providing flexible options for envelope activation. The gate input controls the full ADSR cycle, while the trigger input can be used to re-trigger the attack phase without resetting the entire cycle.
  • Envelope Outputs: Each envelope generator provides an output for the generated envelope signal, which can be routed to control various parameters of other modules, such as VCA, VCF, or oscillator pitch.

Sound Characteristics:

  • Dynamic Control: The 1033 module allows for precise dynamic shaping of audio signals, from sharp, percussive attacks to smooth, sustained sounds.
  • Versatile Modulation: The dual envelope generators enable complex modulation schemes, enhancing the expressiveness and depth of your modular system.


  • Sound Design: Ideal for sound designers looking to shape and control the dynamics of their sounds with precision.
  • Modular Synthesis: Essential for modular synth enthusiasts who need versatile envelope generation for controlling VCAs, VCFs, and other modules.
  • Live Performance: Suitable for live performances, offering hands-on control over envelope parameters and manual triggering.
