CV/Gate

CV/Gate (an abbreviation of Control Voltage/Gate) is an analog method of controlling synthesizers, drum machines and other similar equipment with external sequencers. The Control Voltage typically controls pitch and the Gate signal controls note on/off.

This method was widely used in the epoch of analog modular synthesizers, beginning in the 1960s and up to the early 1980s. It was mostly superseded by the MIDI protocol, which is more feature-rich, easier to configure reliably, and more easily supports polyphony. The advent of digital synthesizers also made it possible to store and retrieve voice 'patches' - eliminating patch cables and (for the most part) control voltages. However, numerous companies – including Doepfer, Buchla, MOTM, Analogue Systems, and others continue to manufacture modular synthesizers that are increasingly popular and rely primarily on analog CV/Gate signals for communication. Additionally, some recent non-modular synthesizers (such as the Alesis Andromeda) and many effects devices (including the Moogerfooger pedals by Moog as well as many guitar oriented devices) include CV/Gate connectivity. Many modern studios use a hybrid of MIDI and CV/Gate to allow synchronization of older and newer equipment.

Famous quotes containing the word gate:

    The sucking milk from this our body sends through
    jolts of light; the son, the father,
    sharing mother’s joy
    That brings a softness to the flower of the awesome
    open curling lotus gate I cup and kiss
    Gary Snyder (b. 1930)
