Doepfer A-140-2 Dual Micro ADSR
- Order number: 180281
- Depth: 40
The A-140-2 contains two classic ADSR envelopes, which can be configured using jumpers. For example, it is possible to determine which parameters are influenced by external control voltages or whether inverted CV signals are emitted in addition to normal signals. – A very clever module!
The module A-140-2 is composed of two identical envelopes. Each modulator features gate and re-trigger inputs as well as four potentiometers for editing the attack, decay, sustain and release phases. Furthermore, there are two CV outputs per envelope. Using jumpers on the circuit board, you can decide what signals are emitted:
- Variant A: Both outputs emit normal envelope signals in the range of 0 to +10 V.
- Variant B: One output emits normal envelope signals, the other works inverted.
In addition, there is one CV input plus attenuator per modulator. Here, you can use jumpers to determine which parameter(s) are to be modulated. – Just the decay? Decay and release? Maybe attack and decay? – You have the choice. On top of that, it is also possible to decide whether time values are to be increased or decreased via control voltages.
Other jumpers determine whether the gate inputs of the envelopes are normalized or not. Furthermore, you can switch the control via bus board on and off.

A-140-2 @Doepfer
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.
