Overview 

The ADSR 120 is one of the core modules essential to an analogue synth. Most frequently used to control a VCA but equally used to control the cut-off of a VCF. Larger systems can expect to have the need for many ADSR modules.

This module, the VC ADSR 121 goes a step further by allowing for dynamic changing of the ADSR timing / level values from external control voltage sources. Additionally, controls are provided to change the response (shape) of attack, decay and release phases. This opens up new possibilities of modulation techniques. 

Features 

  • Controls for Attack, Decay and Release envelope phases along with the Sustain level
  • Controls for the Attack, Decay and Release response shapes from exponential, through linear to logarithmic.
  • Time range selection switch x1 / x10
  • Gate input for full ADSR output
  • Manual gate button
  • LED indicator of gate pulse integrated into the manual gate button
  • Trig input for full AR envelope from a trigger pulse
  • The Trig input can also be used for re-triggering the attack / decay phases whilst the gate input is active
  • CV inputs for each of the Attack, Decay and Release times
  • A common CV input that sets simultaneously the Attack, Decay and Release times 
  • CV input for the Sustain level
