1Voctave

1Voctave is a term used in audio synthesis and music technology to describe a specific control voltage relationship. It refers to a system where an increase of one volt in control voltage results in a doubling of the frequency of an audio oscillator. This logarithmic relationship is fundamental to how many analog synthesizers and modular synthesis systems are designed to produce musical pitches. When a keyboard or sequencer outputs a control voltage to an oscillator, the precise step of the voltage determines the resulting frequency. A one-volt change in this control signal corresponds to a musically significant interval, typically an octave. This standard allows for predictable and controllable musical expression within these electronic instruments. Without this consistent 1V/octave standard, it would be challenging to tune synthesizers accurately or create coherent melodies using external controllers. The widespread adoption of this standard has been a key factor in the historical development and continued relevance of analog and modular synthesizers.
