ERD ModularConjunctio 4-Channel Comparator + Switch

ERD Modular Conjunctio

Conjunctio from ERD is a utility module from their geomantic toolkit, providing four sets of comparators and signal routing switches to provide ample opportunities for creating complex ouroboric feedback control patches. The comparators create gates by comparing the values of two signals, which may then be used externally or to swap the routing of two control signals in the switch section. Conjunctio excels at feedback patching within itself, though even more complex arrangements of signal self-organization are possible when incorporating other modules.

The left side of Conjunctio offers comparators, which compares the signals at each vertical pair of jacks. If input one is higher than input two, the nearby gate output is pulled high, while the inverse will pull the gate output to 0V. The central knobs allow for offsetting the second input, and act as DC offsets when nothing is patched, letting you compare a single signal to a static voltage. On the right hand side, vertical jacks are inputs for two signals, which are routed out the nearby output selectively based on the state of its relevant comparator channel.

While the utilities offered by Conjunctio are simple and straightforward, they are capable of creating complex audio systems with the addition of a few basic waveforms. Taking multiple LFO signals into each comparator will create complex rhythms useful for firing cacophonous sound cannons and ritualistic electronic utterances alike. Use the switched outputs to patch into each comparator's second input, creating flip flopping feedback interactions that usher in a reign of chaos across your modular system. Further experiments may elicit even more profound geomantic discoveries. Whether you're summoning the synth demons for geomantic ends or curious about implementing smart utilities to liven up your gate and signal processing, Conjunctio from ERD is a powerful tool.
