Description
Manufacturer 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).
this module has a maximum current draw of 30ma. it requires 8 te/hp worth of space to fit in a eurorack frame.
