VCV Rack 2.6.0

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).

Recent Releases

2.6.025 Nov 2024 03:15 major feature: Add ability to grab all plugs stacked on a port with the "All cables" menu item. When dropping a plug on a port, always stack it on top of other plugs. Add "View Zoom to fit modules" to menu bar with key command F4. Add "Zoom to fit" to module context menu with key command Ctrl+F4. Add "View Mouse wheel" setting to make mouse wheel zoom instead of scroll. Add parameter value functions `vtobpm()` and `bpmtov()`. On non-QWERTY keyboards, use QWERTY key positions for key commands instead of letters. Render 2-stop linear/radial gradients with any stop offsets and transformations in SVG. Rack Pro. - VST3 plugin forcing DAW MIDI input to channel 1. - Allow VST3 plugin to receive MIDI CC, pitch bend, and channel aftertouch. Core. - MIDI to CV: When sustain pedal is released in monophonic mode, turn off gate if no notes are held. API. - Don't combine SDK packages for Mac-x64 and Mac-arm64. - Update libcurl to 8.10.0 and OpenSSL to 3.3.2. - Add `dsp::MidiParser` class.

2.5.210 May 2024 09:25 minor feature: Add configurable cable color labels. When duplicating module with cables, duplicate cables connected to outputs as well as inputs. Allow building multi-arch x64+arm64 "Universal" Mac binary. Optimize engine's cable stepping algorithm to be as CPU-efficient as non-stackable inputs. Limit log file size to 10 MB. API. - Define `ARCH_*` macros in `arch.hpp` header (included in `rack.hpp`) instead of in compiler flags.

2.5.118 Apr 2024 05:05 minor feature: Remember the last selected cable color from the port's "New cable" menu item. When "Auto-rotate cables" is enabled, the next color in the rotation is used. crash when modules such as VCV MIDI-Map bind parameters. If loaded patch contains unavailable modules, don't Rack after user chooses to open them in VCV Library. Instead, load patch without these modules so user can download them. Add error dialog if moving Rack's user folder to new location fails.

2.5.009 Apr 2024 06:05 major feature: Allow stacking cables on input ports. Cable voltages are summed. Ask to view unavailable modules on the VCV Library when loading a patch. Add "View Cable colors" menu to edit cable colors and disable auto-rotating colors. Add parameter value functions `gaintodb()` (gain factor to decibels), `dbtogain()`, `vtof()` (1V/octave voltage to frequency), and `ftov()`. Move Rack user folder to: - Mac: ` /Library/Application Support/Rack2`. - Windows: `AppData/Local/Rack2`. - Linux: ` /.local/share/Rack2`. Update Mac icon. If Microphone permission is blocked on Mac, show warning dialog on startup. Add `"verifyHttpsCerts"` setting to disable verifying HTTPS certificates. Rack Pro. - MIDI note velocity scale in CLAP adapter. API. - Don't zero output port voltages when disconnecting cables. - `ExpanderChangeEvent` not being dispatched when removing an adjacent module.

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.
