VCV

VCV most commonly refers to VCV Rack, a free, open‑source virtual modular synthesizer that emulates Eurorack hardware inside a computer. It allows users to connect software modules with virtual patch cables to create synthesizers, effects, and audio processing chains.

In VCV Rack, modules perform functions such as oscillators, filters, envelopes, sequencers, and effects. Signals are represented as virtual control voltages (CV) and audio signals; patch cables connect outputs to inputs to create signal flow. The environment runs as standalone software on major desktop platforms, and supports a broad ecosystem of third‑party modules, many offered free and others for purchase.

Historical and community notes: The project is developed as an open‑source platform with contributions from a global community of developers. It gained prominence in electronic music and education for exploring modular synthesis without hardware. As a result, it spawned a large library of modules and related tools, including a store for module packs and interoperability infrastructure for DAW integration.

Other uses: VCV may also stand for venture capital (VC) in business contexts, or refer to other organizations and projects. This article focuses on the VCV Rack music platform, one of the best‑known uses of the acronym.
