VCV Rack 2.4.1

VCV is a virtual Eurorack DAW. VCV Rack is the engine powering VCV modules. Add modules, connect cables, edit parameters, and save/load patches. Create generative patches with your mouse, perform with your MIDI keyboard controller, or connect it to your favorite DAW using the Rack Bridge VST/AU plugin (coming soon). In Rack, control voltages and audio signals are equivalent, so you can modulate parameters with sonic-range VCOs to create customizable FM synths or chaotic wave-shaping oscillators. If you already own a modular synthesizer, you can enhance your setup with an audio interface supporting CV signals or a CV-MIDI-CV interface module with Rack's CV Interface (coming soon).

2.4.126 Aug 2023 07:25 minor bugfix: Improve module browser search order. Library menu plugin update items not being re-enabled when downloading is completed. Rack Pro. - discarded MIDI input messages for all plugin adapters. API. - Add `LightButton` to component library. - Use SSE4.1 intrinsics in `simd::trunc`, `floor`, `ceil`, `round`, and `fmod` to improve performance.

2.4.013 Aug 2023 22:24 major feature: - Add "View Use dark panels if available" menu item. - Show module ID in module's Info menu. - Fix order of input MIDI messages having the same frame timestamp. This fixes *VCV MIDI to CV* from sometimes duplicating clock pulses when transport starts. - Move plugins folder to `/plugins--`. - Core - Add dark panels. - Rack Pro - Add CLAP FX and Generator plugin adapters in addition to existing Instrument plugin. - Fix file dialogs from sometimes loading/saving the wrong Rack plugin instance when multiple instances are running. - Fix crash when using Mac VST3 and AU plugins simultaneously in a DAW. - Fix crash when removing one of multiple running plugin instances in Studio One. - Fix CLAP plugin discarding output MIDI messages. - API - Add `ThemedSvgPanel` and `ThemedSvgScrew` classes which automatically switch SVGs when dark panels are toggled. - Add `"minRackVersion"` property to plugin manifest, which prevents Rack from downloading plugin if version is not compatible. - Fix `ContextCreateEvent` and `ContextDestroyEvent` not defining `vg` NanoVG context.
