VCV has released the 1.0 version of Rack, the open-source virtual modular synthesizer for Windows, macOS, and Linux.

Rack is a powerful standalone modular synthesizer application which can be hooked up to a digital audio workstation using VCV Bridge. It comes with numerous synth modules out of the box, with the ability to import official and third-party expansion modules. The software was first released back in 2017, and the 1.0 release is the most significant update to date.

The latest version of Rack adds numerous new features. Three most essential upgrades introduced in version 1.0 are polyphony, multi-threading support, and undo/redo history. For the full list of changes in Rack 1.0, take a look at the official changelog.

One of the coolest improvements is the introduction of polyphonic cables. Thanks to this new feature, it is now much easier to use VCV Rack as a polyphonic synthesizer. A single patch cable can now transfer polyphonic note data. Multi-threading support is another welcome addition to the feature set, as it allows the app to take full advantage of modern-day CPUs. As for the undo/redo history, users can now experiment more freely because the app can be reverted to the previous state in just a few clicks.

You can download your free copy of VCV Rack directly from the official website linked below. The software works as a standalone application for Windows, macOS, and Linux. Add-on modules can be downloaded or purchased directly from VCV, but you can find many more freeware modules for Rack online.

Rack is available for free download via VCV (4.4 MB download size, EXE installer, standalone application for Windows, macOS, Linux).

    But isnt there still the piggyback option which needs to run the standalone in the background? Not perfect maybe, yet usable & free.

  2. As stated by Andrew Belt the standalone Rack will allways be free and Open Source.

    With Rack 2.0 there will be the additional option to buy a VST version for 99$, but this will not be available before the end of this year.
