based on the popular VCV Rack

Available in AudioUnit/CLAP/LV2/VST2/VST3 plugin formats and as a
standalone app for FreeBSD, Linux, macOS, Windows and the Web.

Open-Source

Created first and foremost as a way to have Rack as a conventional
open-source audio plugin.

Self-contained

Cardinal does not load any external modules, everything is built-in.
