Gt-Res

 jack (input) –  reset, as long as a +5 V input is applied, the active 

Gate at 

jack (27

) and inhibits a new start

 (26)

 (not active in Delay mode); is 

tied by a switching contact to 

jack (33)

 (Env-Gate) and works inverse, 

means a "low" (0 V) at 

jack (33)

 causes a reset! 

33.

 

Env-Gate

 jack (input) –  a +5 V starts the envelope attack or maintaining 

the decay phase; 0 V set the envelope always into the release phase 

34.

 

1 V/Dec.

 jack (input) –  set by an external voltage the Attack time by a 

sensitivity of 1 V/decade, positive/negative voltage -> faster/slower by a 
factor of 10 per volt from the current state 

(35)

 

35.

 

Attack

 controller –  set the Attack time between 100 µs to 20 seconds 

36.

 

LED indicator

 –  shows by its brightness the current envelope output 

value during the attack phase, "green" at positive output values, "red" for 
negative ones 

37.

 

Env-Res

 jack (input) –  reset by a 0 V -> +5 V transition the envelope 

output to 0 V and the generator back to the attack phase; is tied by a 
switching contact to 

jack (33)

 (Env-Gate) and causes a reset with the 

envelope start 

38.

 

Hold

 jack (input) –  "freezes", as long as a +5 V signal is applied and held, 

the envelope output to the current voltage state 

39.

 

1 V/Dec.

 jack (input) –  set by an external voltage the Decay time by a 

sensitivity of 1 V/decade, positive/negative voltage -> faster/slower by a 
factor of 10 per volt from the current state 

(40)

 

40.

 

Decay

 controller –  set the Decay time between 100 µs to 20 seconds 

41.

 

Dec-Act.

 jack (output) -  provides a +5 V signal during the decay phase 

42.

 

LED indicator

 –  shows by its brightness the current envelope output 

value during the decay phase, "green" at positive output values, "red" for 
negative ones 

43.

 

Sustain

 controller –  set the final value of the decay phase between  

-100% (-5 V) und +100% (+5 V) 

44.

 

CV-Sus

 jack (input) -  set by an external voltage of -5 V - +5 V (at middle 

position of 

(43)

) the final value of the decay phase between -200% (-10 V) 

und +200% (+10 V); decay becomes at >100% a second attack! 

45.

 

LED indicator

 –  shows by its brightness the current envelope output 

value during the release phase, "green" at positive output values, "red" for 
negative ones 

46.

 

Release

 controller –  set the release time between 100 µs to 20 seconds 

47.

 

1 V/Dec.

 jack (input) –  set by an external voltage the release time by a 

sensitivity of 1 V/decade, positive/negative voltage -> faster/slower by a 
factor of 10 per volt from the current state
