VCV Rack


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

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 ; 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.
