<Li> Volts per octave was popularized by Bob Moog in the 1960s , and was widely adopted for control interfacing . 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 . Companies using this CV method included Roland , Moog , Sequential Circuits , Oberheim and ARP . This convention typically had control modules carry the source voltage ( B+ , 5v ) on the ring of a TRS jack , with the processed voltage returning on the tip . However , other manufacturers have used different implementations with voltages including - 5 to 5v , 0 to 5v , 0 to 10v with the B+ possibly on the tip . This makes interoperability of modules problematic . </Li>
