Envelope Controlled VCA

Module A-142-3 is the combination of a simple AD/AR envelope generator and a VCA behind a front panel with 4HP only.

The type of envelope can be selected by means of a toggle switch between A/D (Attack-Decay) and A/R (Attack/Release). Another toggle switch is used to choose envelope or (free running) LFO mode. The envelope output controls a linear VCA.

These controls and in/outputs are available:

  • Attack control
  • Decay/Release control
  • AD/off/AR switch
  • Envelope/LFO switch
  • LED (envelope display)
  • Gate Input
  • Manual gate (momentary switch)
  • Envelope Output
  • VCA CV Input (normalled to Envelope Output)
  • Audio Input with Level control
  • Audio Output (the outputs of several A-142-3 can be internally mixed together)
  • ? mA +12V
  • ? mA -12V
  • ? mA 5V

This Module is a prototype or in a concept phase.
