Such a method implies that the synthesizer is monophonic. CV can also control parameters such as rate, depth and duration of a control module. In the case of triggering a drum machine, a clock signal or LFO square wave could be employed to signal the next beat. While the concept of CV was fairly standard on analog synthesizers, the implementation was not.
One volt represents one octave, so the pitch produced by a voltage of 3v is one octave lower than that produced by a voltage of 4v. Notable followers of this standard include Roland, Moog, Sequential Circuits, Oberheim and ARP.
