Description

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, min. level +5V, max. level +12V
  • 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. The gate levels in the “high” state have to be at least +5V (up to +12V). The “low” state has to be 0V or less. Only signals with fast rising slopes (“rectangle type”) are suitable as gate signals. Slowly changing signals (e.g. triangle) cannot be used as gate signals.

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)
