The long-awaited polyphonic mixer A-135-5 is now finally available since the end of 2023. Yes, of course you could already make do with A-130-8 VCAs, for example. Some poly fans also installed a series of A-138n narrow mixers or A-138f dual crossfaders, but of course it wasn’t all that elegant. The A-135-5 mixer is elegant. … Read more
The A-190-5 is a Midi-to-CV/Gate interface primarily intended for polyphonic applications. This means that up to four modular synthesizer voices can be controlled via any midi keyboard. Polyphony is still a rather exotic “fringe phenomenon” in the modular area. Effort, cost and complexity to control such a system appear relatively high compared to modern analog … 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 family of A-111 oscillators now includes an impressive 6 variants, all of which use the Curtis chip CEM3340 (or replica) with its triangular core and allow very precise tracking over 10 octaves and more. The A-111-4 is – nomen est omen – designed fourfold and also has a common “master” section, which affects all … 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
