Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

VCV Rack is a virtual Eurorack-style modular synthesizer for desktop music production. It is suited to modular-synthesis learners, sound designers, performers, composers, and developers creating Rack modules. The standalone application runs on Windows, macOS, and Linux, with virtual modules for audio, control voltage, MIDI, oscillation, filtering, sequencing, and effects. Its open-source foundation and C++ SDK also give developers a path to create custom modules.

Pricing is split between Rack 2 Free and Rack 2 Pro. Rack 2 Free is a free standalone application with free modules and community support. Rack 2 Pro costs $149 as a one-time purchase and adds free and Pro modules, professional support, and DAW plugin operation through VST2, VST3, Audio Unit, and CLAP. The paid tier also supports parameter automation in a DAW and offline audio rendering, making it the relevant choice for users who want to place Rack inside a production environment rather than run it only as a standalone application.

VCV Rack’s strongest fit is an Eurorack-style workflow with flexible routing and a wide host ecosystem. It supports polyphonic audio, CV, and MIDI routing, an online module library, and integrations including Ableton Live, Cubase, FL Studio, Reason, Bitwig, Reaper, Mixbus, Studio One, Cakewalk, Logic Pro, and GarageBand. Choose it for virtual modular patching, custom module development, or a free starting point. Choose another synthesizer if you want an integrated, non-modular instrument or AI features.
