Dual VC ADSR ttt





Dual voltage controlled ADSR generator. Constant slope. Transistor core. 22HP.




  • Two identical ADSR generators.
  • Attack range 0.1ms - 10s.
  • Decay and Release ranges 0.5ms - 20s.
  • Constant slope action.
  • 4 state leds show each step of the ADSR.
  • Linear or exponential slopes selectable by switches.
  • Voltage control on each stage and output amplitude.
  • Attenuators for each CV input.
  • Sustain gate output produces gates during sustain time.
  • Cycle mode. Sustain must be at zero. Attack controls rising slope. Decay controls falling slope.
  • Lev1 and Lev2 knobs control output levels when Lev1 and Lev2 inputs are not used. Or they attenuate Lev1 and Lev2 inputs when they are used.
  • Trigger input resets the envelope.
  • Power consumption: V+ 76mA, V- 72mA.
