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
