> Cardinal 22.09 released
On 2022-09-20 by falkTX

Greetings everyone, we have yet another release of Cardinal, with a good set of bugfixes and a few nice to have features.
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 changes for this release, besides the fixes, are a dark vs light mode switch, CardinalNative build, finishing VST3 support and an initial CLAP version.
There are a couple of new module collections and updates to existing ones too.



  • Add CardinalNative standalone build (uses native audio from the system instead of JACK)
  • Add CLAP plugin version (fx and synth variants only, for now)
  • Add dark mode switch in View menu, enabled by default
  • Add readme and license to zip/tar releases
  • Add linux-riscv64 build
  • Add -Wno-format-security to build flags
  • Fix AU plugin crash when host does not provide time signature (x64 auval)
  • Fix AU plugin not updating for buffer-size and sample-rate changes
  • Fix VST2 crash when removing 1 of many similar instances
  • Fix VST2 and VST3 initial UI size in some hosts
  • Fix VST3 remaining issues and mark it as stable (only CV ports need attention, but no Host/DAW that I know implements these)
  • Fix memory corruption and leaks when loading and removing modules
  • Fix Bidoo not saving non-parameter data
  • Fix Bidoo limonade crashing when canceling its save dialog
  • Fix Ildaeil log sliders, allow mono input plugins
  • Fix/remove stray Carla module from "DRMR - Interverb.vcv" example patch
  • Split main variant audio IO in 4 stereo groups
