A-100 analog modular Website
I often used my A-111-5 as a “stopgap” when I quickly needed another simple synthesizer voice and maybe was just too lazy to patch extra VCO, VCF, VCA, ADSR and LFOs for such a secondary voice . I was often plagued by the “guilty conscience of the modularist” when I ignored the far-reaching possibilities of … Read more
The “Slim Line” module is a version of the classic analogue noise generator A-118-1 reduced to half the width (only 4HP). As with the other “Slim Line” modules, slightly smaller buttons and sockets with narrow, round nuts are also used here. The controls are at the top and the sockets are at the bottom, which … Read more
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 A-149-4 module is now the third member of the “A-149 family”. All three modules are about generating random voltages or trigger signals that go well beyond the possibilities of the random/noise modules A-118-1, A-118-2 or A-117. The A-149-1, which is based on the Buchla module 266, already has quantized voltages available that can be … 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-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-141-4 is a quadruple ADSR that is only 8 TE wide and is primarily intended for polyphonic applications. Therefore, there is only one set of controls for the envelope’s parameters – attack, decay, sustain and release, which affect all four envelopes equally. In addition, we find four control voltage inputs with bipolar attenuators for … Read more
The A-105-4 is a polyphonic filter module based on the SSM2024 integrated circuit (or its replica SSI2144). In principle, we have four A-105 filters with a common control in front of us: Cutoff frequency, resonance (called “Q” here) and input level can be set in the same way for all four filters or also controlled … 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
