A-141-4 is a quad voltage controlled Envelope generator and is primarily planned for polyphonic applications. The module contains four ADSR type voltage controlled envelope generators with exponential curve shapes (charge/discharge curves of a capacitor). Common manual controls and CV inputs with polarizers are available for the parameters Attack (A), Decay (D), Sustain (S) and Release (R). Each of the four envelope generators has available a gate input, a control LED and an envelope output.
The module has these controls and in/outputs are available:

  • Attack (manual control)
  • Decay (manual control)
  • Sustain (manual control)
  • Release (manual control)
  • CVA control (polarizer for Attack CV input)
  • CVD control (polarizer for Decay CV input)
  • CVS control (polarizer for Sustain CV input)
  • CVR control (polarizer for Release CV input)
  • CVA socket (Attack CV input)
  • CVD socket (Decay CV input)
  • CVS socket (Sustain CV input)
  • CVR socket (Release CV input)
  • Gate inputs 1 - 4
  • Envelope outputs 1 - 4
  • LED displays 1- 4 (envelope display)
  • The output voltage range for each envelope is 0 - 10V.
  • The time range of Attack/Decay/Release is about 1ms to 30s.
  • Release (manual control)
  • CVA control (polarizer for Attack CV input)
  • CVD control (polarizer for Decay CV input)
  • CVS control (polarizer for Sustain CV input)
  • CVR control (polarizer for Release CV input)
  • CVA socket (Attack CV input)
  • CVD socket (Decay CV input)
  • CVS socket (Sustain CV input)
  • CVR socket (Release CV input)
  • Gate inputs 1 - 4
  • Envelope outputs 1 - 4
  • LED displays 1- 4 (envelope display)
  • The output voltage range for each envelope is 0 - 10V.
  • The time range of Attack/Decay/Release is about 1ms to 30s.

Function of the polarizers:

  • a positive control voltage applied to the socket CVA/CVD/CVR reduces the time adjusted by the manual A/D/R controls when the CVA/CVD/CVR control is right from the center position
  • a positive control voltage applied to the socket CVA/CVD/CVR increases the time adjusted by the manual A/D/R controls when the CVA/CVD/CVR control is left from the center position
  • a positive control voltage applied to the socket CVA reduces the sustain value adjusted by the manual S control when the CVS control is right from the center position
  • a positive control voltage applied to the socket CVA increases the sustain value adjusted by the manual S control when the CVS control is left from the center position

Application:

  • polyphonic patches (four envelope generators with the same envelope parameters to control four VCFs, VCAs or other modules)

Width: 8 HP / 40.3 mm
Depth: 45 mm
Current: +70mA (+12V) / -60mA (-12V)
