A-116 VC Waveform Processor

“Processor” here does not mean a processor in a computer, but simply an (analog) circuit that can change waveforms. Here the input signal is processed by two parallel circuits, the results of which are then mixed together: a clipper, which cuts the input signal sharply above a threshold, and a polarizer/attenuator, which can both attenuate … Read more

A-144 Morphing Controller

The module is no longer in production. The A-144 Morphing Controller generates control voltages that are used, for example, to regulate four linear VCAs of a voltage-controlled mixer in such a way that the four input signals of the mixer are morphed one after the other. The A-135-1 or A-135-2 Voltage Controlled Mixer and the … Read more

A-168-1 PWM Generator

The A-168-1 is a small auxiliary module that generates a square or pulse oscillation that can be modulated in width for LFOs or VCOs without a square/pulse. This is an interesting feature for LFOs in particular, since almost all LFOs can generate a fixed, symmetrical square wave (at least the A-146 is capable of manually … Read more

A-167 Analog Comparator / Subtractor / Offset Generator

The module is no longer in production. The A-167 Analog Comparator can compare voltages with each other and generate a gate signal. There are many possibilities: comparison of two external voltages, comparison of a voltage (normal or inverted) with a positive or negative threshold value, comparison of the difference between two external voltages with a … Read more

A-172 Maximum / Minimum Selector / Rectifier

The module is no longer in production. The A-172 maximum/minimum selector leaves many “modularists” at a loss at first. A module that selects and makes available both the maximum and the minimum voltage from up to four input signals may appear too “mathematical” or intricate. In fact, the module is a surprisingly easy-to-use tool for … Read more
