Cardinal is a free, open-source virtual modular synthesizer based on VCV Rack, packaged as a self-contained audio plugin (AudioUnit/CLAP/LV2/VST2/VST3) and standalone app. It bundles 1382 modules in a single binary without loading external modules or connecting to the official Rack store.

Use cases

• run a modular synth inside my DAW as a plugin
• use VCV Rack as an open-source audio plugin
• patch virtual eurorack modules without external dependencies
• send CV/gate signals between my DAW and hardware modular via LV2
• learn modular synthesis for free
• run a modular synth in the browser or on FreeBSD

When to choose

• you want VCV Rack as a self-contained, fully open-source plugin in your DAW
• you need real CV port support via LV2 for hybrid modular setups
• you want a huge built-in module library with no external module loading
• you need cross-platform support beyond the usual three desktop OSes

When to avoid

• you need to load third-party modules from the official VCV Rack library/store
• you require stable CLAP support or VST3 plugin hosting, both still experimental
• you need signed installers or official vendor support on macOS/Windows
