The A-141-2 module is an ADSR envelope generator with voltage controlled attack, decay, sustain and release parameters. Other features include LFO functionality as well as digital end-of-attack and end-of-release outputs. Besides positive and inverted outputs there is an output with voltage controlled amplitude available.
Attack, Decay, Sustain and Release parameters of the A-141-2 can be adjusted manually as well as via control voltages. The CV inputs come equipped with attenuators. In addition, a Comm-CV socket was implemented. Control voltages fed to this input influence all time parameters (A, D and R) simultaneously. Thus, it is possible to make high pitched notes shorter and more percussive. – Just like the behavior of many acoustic instruments. The time range of the envelope goes from 50 microseconds to six seconds. Using a toggle switch, it is possible to increase these values by a factor of ten (500 µs to 60 s) or a factor of hundred (5 ms to 10 min). To activate the envelope, there are gate and retrigger inputs.
The A-141-2 is equipped with a normal and an inverted output. Both connectors work with a fixed level. Furthermore, there is a third, variable output. Here, before reaching the out socket, the envelope signal is fed to a voltage controlled VCA. – Perfect for velocity CV signals. A jumper on the circuit board allows you to choose between a unipolar and a bipolar mode of operation. Other jumpers make it possible to normalize the CV inputs.
Last but not least, there are two digital outputs called EOA and EOR, which emit a gate signal after the attack respectively release phase. This is useful for delayed triggering of other envelopes. By connecting EOA or EOR output to the gate input, you can make the A-141-2 oscillate like a LFO. Adjustments to the envelope times change the frequency and waveform. If you connect the Attack CV input to the inverted output or the Decay respectively Release CV input to the normal output, you can alter the curve characteristics.

WIth a long trajectory building synths, MIDI keyboards and designing bespoke devices for music pioneers Kraftwerk, Dieter Doepfer decided to design his own modular synthesizer in 1995 based on existing electrical and mechanical specifications of lab equipment he used during his years at university. The official presentation of the system at 1996 Frankfurt Musikmesse caught everyone by surprise and created lots of interest. After Doepfer published the specifications on his website, many instrument designers and engineers saw the potential of the new Eurorack format. Doepfer continues expanding their catalog of over 200 modules (and counting), operating from their modest offices in the outskirts of Munich.
