AND Function

« Back to Glossary Index

The “AND” logic function refers to a binary operation that takes two input signals, typically represented as gate or trigger signals, and produces an output signal based on whether both input signals are active (high) or not. The AND function returns an active (high) output only when both input signals are active at the same time; if either or both of the input signals are inactive (low), the output is inactive (low).

In a modular synthesizer or other synthesis environment, the AND logic function is often implemented in a dedicated logic module or within a more complex module that includes various logic functions. These logic modules can be used to create complex rhythmic patterns, gate sequences, and modulation signals by combining and processing multiple input signals.

Here’s an example of how an AND logic function might be used in a modular synthesizer patch:

  1. Two gate or trigger signals, generated by sequencers, clock dividers, or other rhythmic sources, are fed into the inputs of an AND logic module.
  2. The output of the AND logic module will be active (high) only when both input signals are active simultaneously.
  3. The resulting output signal can be used to control other modules in the synthesizer, such as triggering an envelope generator, advancing a sequencer, or modulating a parameter.

By using the AND logic function, a musician can create new rhythmic patterns and modulation signals that are derived from the interaction of multiple input sources. Logic functions, including AND, are essential tools in modular synthesis and can greatly expand the creative possibilities of a patch.
