OR Function

« Back to Glossary Index

An OR function is a logic operation that compares two or more input signals and produces an output signal based on the presence of a high or “on” state in any of the inputs. It’s commonly used in modular synthesizers with control voltage (CV) or gate signals for creating more complex modulation, sequencing, and triggering events.

An OR function can be represented as follows:

Output = Input A OR Input B

The output will be high (or “on”) if either Input A, Input B, or both are high (or “on”). If both inputs are low (or “off”), the output will also be low (or “off”).

In a modular synthesizer, OR functions can be performed by dedicated logic modules or specific sections within more complex modules. By combining multiple input signals using the OR function, you can create new rhythmic patterns, control multiple events with a single trigger, or combine modulation signals to affect a single parameter.
