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.
