What does the acronym FM CV mean in relation to electronic music production?

In electronic music production, the acronym FM CV stands for Frequency Modulation Control Voltage. It refers to a method of synthesizing sounds where the frequency of one oscillator (the modulator) is varied by an incoming control voltage to affect the pitch and timbre of another oscillator (the carrier). This technique is widely used in synthesizers to create complex and evolving sounds, allowing for a rich palette of tones and textures in music production.
