CV gates
An AI version what CV gates are
CV/Gate is an analog control protocol used in synthesizers and modular systems to communicate pitch and timing information between devices. It relies on two distinct voltage signals: Control Voltage (CV) and Gate.
Control Voltage (CV) carries a continuous analog voltage that typically represents pitch. The most common standard is 1V per octave, meaning an increase of one volt raises the note by one octave. This signal is routed to oscillators to determine the frequency of the sound.
Gate is a digital-style pulse (usually 0V to 5V) that indicates note on/off status. When the gate signal goes high (e.g., a key is pressed), it triggers the envelope generator to start the attack and sustain phases. When the gate drops low (key released), the envelope enters the release phase.
Unlike MIDI, which is a digital protocol that sends data packets over a single cable and supports polyphony, CV/Gate uses separate cables for each voice. This makes traditional CV/Gate setups inherently monophonic (one note at a time) unless multiple converters are used. While largely superseded by MIDI in the 1980s, CV/Gate remains essential for Eurorack modular synthesizers and many semi-modular analog instruments, offering immediate, tactile control with minimal latency.
