VCV Rack serves as the core engine for VCV's modular synthesizer environment, allowing users to add modules, connect virtual cables, and adjust parameters to build custom patches. This platform enables the creation of generative sequences with intuitive mouse controls or live performances using a MIDI keyboard controller. Integration with popular digital audio workstations is also supported through the upcoming VCV Bridge plugin, expanding its utility within professional music production workflows.

Within this modular system, control voltages and audio signals share the same format, allowing seamless modulation across parameters. This design enables the construction of highly customizable frequency modulation synthesizers and complex wave-shaping oscillators, providing a rich sonic palette. Users can experiment with intricate sound design by leveraging the unique interaction between control and audio signals, pushing the boundaries of traditional synthesis.

For those with existing hardware modular synthesizers, VCV Rack offers the ability to enhance setups through external interfaces, such as audio interfaces or CV-MIDI-CV converters. The forthcoming CV Interface module will further facilitate integration between software and hardware, enabling hands-on control and expanded performance possibilities. This makes VCV Rack a powerful tool for both studio production and live electronic music environments.
