VCV Rack is a free and open-source cross-platform software modular synthesizer.


VCV Rack is a free open-source virtual modular synthesizer: multiple modules can be connected to synthesize a sound. By default the software contains several VCOs, LFOs, mixers, and other standard synthesizer modules, however more can be added as plugins through the VCV Rack website.[5][6]

Version 1.0.0 added a stable API, a multithreading engine[7] and support for polyphonic signals.[8]


In addition to the above features, VCV rack can also connect to other hardware and software by outputting analog CV/gate and digital USB or MIDI signals. The software can also connect to other VST plugins though the module "host"; the ability to use VCV rack as a VST plugin itself was a feature that has been deprecated but is expected to return shortly after the release of Rack v2.[9]
