Rack is the engine powering VCV modules. It lets you add modules, connect cables, edit parameters, and save/load patches. You can create generative patches with your mouse, perform with your MIDI keyboard controller, or connect it to your favorite DAW. 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.
