DISTRHO Cardinal Rack v25.06 LiNUX WiN macOS [FREE]

Cardinal is a free, open-source modular synthesizer plugin that brings a complete virtual rack environment directly into your DAW. Built from the same codebase as VCV Rack but designed as a fully self-contained plugin, it bundles a large collection of third-party modules and internal utilities in a single binary—no external module loading or online store required. You get three plugin variants (main, Synth, and FX) to fit different host requirements, with MIDI input/output support across all versions. The main variant offers 8 audio I/O and 10 CV ports, while Synth and FX variants provide 2 audio outputs and 2 audio I/O respectively. Available as VST2, VST3, and AU for Windows and macOS, Cardinal is ideal for hobby producers who want to explore modular patching inside FL Studio, Ableton Live, or Logic Pro without committing to a separate standalone application. It includes modules from well-known developers like Befaco, Bogaudio, ChowDSP, Impromptu, and Valley, covering oscillators, filters, sequencers, effects, and utilities. Whether you’re building generative patches, processing audio, or designing custom synth voices, Cardinal gives you a flexible, free modular toolkit that runs right in your session.
