The A-138f is a small, dual, three-way crossfader. “Three-way” here means that we have three possible input signals and one output signal. You will look in vain for the extremely sophisticated options of the A-138e, which unfortunately is no longer manufactured. The A-138f simply fades between two signals “A” and “B” and then (from the … Read more
The module is small and interesting. A stripped down to two parameters but still flexible envelope generator with voltage control, hardwired to a linear VCA, plus a ducking function. The whole thing is also designed twice on only 8 HP. This is made possible by the new “Slim Line” format with slightly smaller buttons and … Read more
The A-150-8 is a very extensively equipped module that provides a total of 8 programmable 1:2 or 2:1 switches. What is programmable? Two LEDs per switch indicate which of the two “I/O” sockets on the left is connected to the “O/I” socket on the right. So we can either switch between two input signals at … Read more
The A-132-3 Dual Lin. / Exp. VCA has two identical sub-modules. Both amplifiers can be switched independently between linear and exponential characteristics. In addition, there is a clear and solid equipment (CV input with attenuator and manual “gain” control), so that the module is very versatile. User interface Inputs (for each of the 2 sub-modules): … Read more
The A-150-1 Dual Voltage Controlled Switch has two identical submodules. Each of the submodules is a bidirectional 2:1 switch, i.e. inputs and outputs can be swapped in this module. This gives us two possible uses: The choice of which input is connected to the output or which output is connected to the input is made … Read more
The A-155 Analog / Trigger Sequencer is a well-equipped 2 x 8 step sequencer with three trigger tracks, one gate track and two control voltage tracks. Triggers 1 and 2 are always alternative, as are trigger 3 and the gate signal. Separate settings for “glide” (portamento) can be made for the two control voltages. In … Read more
A Lowpass Gate (LPG) is an odd device. It uses a vactrol circuit and couples a low pass filter to an amplifier (VCA). Then why not just use a filter and an amplifier separately? The LPG can be switched between VCF, VCA and the combination VCF / VCA! In addition, the module is built with … Read more
The A-133-2 is a dual voltage controlled polarizer, meaning its input signals (audio or control voltages) can be amplified like a traditional VCA. With a negative control voltage or a corresponding manual setting, the input signals are amplified in inverted form. An input, a control voltage input, an output, as well as a manual controller … Read more
The A-132-8 is a module designed for polyphonic operation with 4 voices with a total of 8 VCAs. Why so many VCAs, one might ask, wouldn’t 4 be enough? Two VCAs connected in series are responsible for each of the four synthesizer voices on the A-132-8: The first VCA always works linearly, the VCA afterwards … Read more
