CV is control voltage used to transmit continuous electrical signals between electronic instruments and modules. It allows parameters such as pitch, filter cutoff, amplitude, and modulation to be controlled in a fluid, analogue manner. CV is fundamental to modular and semi-modular systems, enabling direct, real-time interaction between sound sources, controllers, and processors.
A module is a self-contained unit designed to perform a specific function within a larger system. Modules are commonly used in modular and Eurorack setups, where each unit handles tasks such as sound generation, modulation, filtering, or control, allowing systems to be built and expanded piece by piece.
New Gear is unused and in original condition, supplied as it leaves the manufacturer. It is chosen for guaranteed reliability, full functionality, and the assurance of manufacturer support. For example, buying new ensures access to the latest design revisions, included accessories, and official warranty coverage.
Stereo is a two-channel sound format that uses separate left and right signals to create a sense of width and space. It is used to place sounds across the listening field, making music feel more immersive and detailed. For example, a stereo synth or effect can spread a pad or texture across both channels, giving a track greater depth and separation compared to a mono signal.
