Module A-142-1 is a voltage controlled envelope generator. The only time parameter is decay (like a TB-303).
Decay may be adjusted manually and via voltage control input (with attenuator). The envelope output is displayed with LED control. Additionally from the envelope signal a Gate signal and an inverse Gate signal with adjustable threshold is derived. LED control for Gate output. Thus one obtains a voltage controlled Gate additionally or alternatively to the envelope signal with voltage controlled duration. The attack time is fixed to about 0.2 ms, the shortest decay time is about 2 ms. By changing the value of a capacitor the shortest time can be modified.
