Product Description

Module A-142-4 contains four simple envelope generators. The only time parameter is Decay and can be adjusted manuall by means of the Dec. control in the range 2 ms … 2 seconds. The attack time can be adjusted internally by means of a separate trimming potentiometer for each sub-unit in the range 1 ms … 15 ms. The factory setting is about 3 ms. This is the attack time of the TB303. Each envelope output has a LED control available. The trigger inputs are normalled (1 -> 2 -> 3 -> 4).

 

Suggestions for modifications:

 

  • Each sub-unit has a pin header with two pins available. When the two pins are shortened (e.g. by means of a jumper or a toggle switch connected to the two pins) the corresponding sub-unit changes to a loop mode. In this mode the unit is triggered by itself like an LFO..

  • 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)
