Doepfer A-142-2 Dual Envelope Controlled VCA


Module A-142-2 contains two envelope controlled VCAs behind a front panel with 8 HP only. Each of the two sub-units is the combination of a simple AD/ADSR/AR envelope generator and a VCA. The type of envelope can be selected by means of a toggle switch:

  • AD: Attack-Decay
  • AR: Attack-Release
  • ADSR: Attack-Decay-Sustain-Release with the limitation that Decay Time = Release Time and fixed Sustain level (factory setting 50%)

Each sub-unit provides these controls and in/outputs:

  • Attack (A), manual control
  • Decay/Release (D/R), manual control
  • Mode switch (AD, AR, ADSR)
  • Audio level control (small control without knob)
  • CVT Input (CVT = CV Time)
  • Attenuator for CVT (small control without knob)
  • Gate Input
  • Manual Gate (momentary switch)
  • Audio Input
  • Audio Output
  • Envelope Output
  • LED control (envelope display)

By means of two internal jumpers for each sub-unit one can select which parameter(s) are controlled by the CVT input (e.g. D+R only or A only or A+D+R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question).
Two more jumpers are used for the optional bus access to the gate signal of the bus for each envelope.

Applications: virtually in each patch one or more envelope/VCA combos together with a sound source are very useful, mainly for percussive sounds
