Description

Module A-142-6 is a simple envelope generator which can work also as an LFO. For the switching between envelope and LFO the toggle switch "Loop" is used. When in position "off" the unit works as an envelope generator and the envelope is triggered by the positive edge of the trigger signal applied to socket "Trig.". When the Loop switch is in position "on" the unit works as an LFO.
When a trigger signal is applied in LFO mode the envelope and LFO signals interfere with each other.
The unit is equipped with "Attack" and "Decay" controls. These are used to adjust the attack (rise) and decay (fall) time manually in the range 2 ms ... 2 seconds (?).
The signal appears at the envelope/LFO output "Out". The peak voltage is about +10V. The output signal is displayed by an LED.

Suggestions for modifications:

• By changing the value of a capacitor the time range can be modified (e.g. 0.2 ms ... 0.2 seconds or 20 ms ... 20 seconds)
