Software modular VCV Rack just hit a major milestone – it’s now officially version 1.0, with polyphony, full MIDI, module browsing, multi-core support, and more. And since it’s a free and open platform, you don’t want to sleep on this.

VCV Rack is an open-source software modular platform, featuring a Eurorack-inspired user interface. VCV Rack is available for Linux, Mac & Windows as a free download. Additional modules for the platform – both free and commercial – are also available.

Here are the features new to V1.0

Polyphony. Use up to 16 voices with the full flexibility of modular patching. Cables automatically turn polyphonic when requested by MIDI modules, sequencers, etc.
MIDI output. Control MIDI hardware with Rack modules. New modules include CV-GATE for drum machines, CV-MIDI for desktop synths, and CV-CC for Eurorack interfaces.
MIDI mapping. Control knobs, buttons, and sliders directly from a MIDI controller. Using the new MIDI-MAP module, click a virtual parameter and move a hardware control to create a mapping.
Module Browser. Search, filter, and view modules in your collection. Click and drag to directly place modules in the rack.
Multi-core engine. Use multiple CPU threads to maximize the number of modules. Accelerated polyphonic engines on many VCV and third-party modules.
Dozens of other new features and fixes, including manual parameter entry, module disabling, module “force” dragging, module expanders, easy zoom gestures, and more.
