> Cardinal 23.09 released
On 2023-09-17 by falkTX

Hello again everyone, it is time for another Cardinal release.
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.

The main change for this release is making the OSC remote control an official feature, with some initial documentation here.
Then also the usual set of fixes and a few module updates.
As an extra, Cardinal has its own website now, living at cardinal.kx.studio with the online/wasm version still accessible by clicking "Try Live".


  • Add OSC Remote control
  • Do not try to save and load module info per project, its a global setting since 22.07
  • Fix a few missing details in macOS app bundles
  • Fix Cardinal Mini window title after loading patches
  • Fix crash when pressing F9 (used internally for generating screenshots)
  • Fix crash when window creation fails (e.g. running headless)
  • Fix headless build when OpenGL is available (but unused since it is headless)
  • Fix stuck notes in CardinalNative MIDI handling
  • Fix VST2 parameter changes
  • Proper handling of XDG_DOCUMENTS_DIR
  • Switch to regular/initial welcome patch for web/wasm builds
