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]

An open-source virtual modular synth featuring software versions of some of the most popular Eurorack modules on the market is available to download for free.

VCV Rack isn't the only software modular available: Native Instruments' Reaktor Blocks and Softube's Modular offer users their own virtual Eurorack system, but these come with a hefty price tag. VCV Rack can be downloaded for free on Linux, Mac and Windows platform, with the source code available at Github.
