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

Overview

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.56

Version 1.0.0 added a stable API, a multithreading engine3 and support for polyphonic signals.7

Version 2.0.0 was officially announced in September 20218 and released on November 30, 2021.3

Interconnectivity

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 itself as a VST plugin within other audio applications was added upon the release of Rack 2.0.9
