On 2022-04-05 by falkTX

Hello everyone, yet another release of Cardinal is here, this time focused on bugfixes.
Cardinal is a free and open-source virtual modular synthesizer plugin.
It is based on the popular VCV Rack but with a focus on being a fully self-contained plugin version.



  • Add Interverb demo patch (in source code)
  • Add retrigger to Host-MIDI
  • Do not show resize handle on JACK Standalone
  • Fix and enable ChowDSP Credit module
  • Fix potential noise burts on load with ihtsyn MVerb-based modules
  • Fix messed up graphics on Windows with High-DPI screens
  • Fix resources not found on some Windows systems (by not relying on environment variables)
  • Fix several Windows UTF-16 issues
  • Fix X11 file dialogs not appearing on some systems (auto-activate needed DBus portal)
  • Fix VST3 state under some hosts
  • Make JACK Standalone more useful on Windows (log to console when possible, show error dialog if JACK not running)
  • Optimizations to core modules and headless build
  • Refresh default template, add FX and Synth specific template variants
  • Tweak Host-MIDI default parameters


The source code plus Linux, macOS and Windows binaries can be downloaded at https://github.com/DISTRHO/Cardinal/releases/tag/22.04.
Cardinal is released as LV2, VST2 and VST3 plugin, plus AudioUnit and JACK standalone for certain systems.
The VST3 version is still considered experimental, prefer to use LV2 or VST2 if possible at this time.
