In their own words
Cardinal
Cardinal is a free, open-source modular synthesizer based on VCV Rack, available as a standalone app and as a plugin. It bundles 1,382 modules from 84 authors or brands, but does not load external modules or connect to the official Rack library or store; modules cannot be added to an existing build. Cardinal runs on Linux, macOS, Windows, and the web. Its plugin formats are AudioUnit, CLAP, LV2, VST2, and VST3, with Main, Synth, and FX variants that all support MIDI input and output. Main provides eight audio inputs and outputs and ten CV inputs and outputs, but is unavailable in AU and VST2 and is not yet available in CLAP. Mini has a smaller hand-picked module selection, two audio ports, and five CV ports, and is available only as LV2 or standalone. OSC remote control works in standalone use, not in the plugin. The project describes Cardinal as stable, while noting CLAP support is still in progress and VST3 hosting inside Carla or Ildaeil is experimental. It is licensed under GPLv3+.
