A classic dual ADSR from the originators of Eurorack. Redundant module from my setup.

Description from Modular Grid

Dual Micro ADSR

Module A-140-2 contains two ADSR type envelope generators behind a front panel with 8 HP only.

Each ADSR provides these controls and in/outputs:

  • Attack (A), manual control
  • Decay (D), manual control
  • Sustain (S), manual control
  • Release (R), manual control
  • Gate Input
  • Retrigger Input
  • CVT Input with attenuator (CVT = CV Time)
  • Envelope Output 1
  • Envelope Output 2
  • LED control

By means of internal jumpers one can select which parameters are controlled by the CVT input (e.g. D only or D+R or A+D+R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question).

By means of another jumpers output 2 can be set to normal or inverted envelope). Two more jumpers are used for the optional bus access to the gate signal of the bus for each ADSR.
