VST/AU support will be added with the “VCV Bridge” module in Rack v0.6.0, scheduled for release in late January 2018.
Rack itself won’t be a VST/AU plugin because of the major limitations of these formats, but instead you’ll be able to connect Rack to your main DAW by adding the lightweight VST/AU Bridge plugin to as many DAW channels/tracks as you like, which will each connect an equal number of Bridge modules in Rack. This cross-application method allows you to break the mindset of mixing linearly in your DAW and instead use nonlinear methods like cross-modulation between tracks, enveloping audio to control filters and sidechain compressors, etc. The Bridge protocol will be fault tolerant and will not matter which order you open the DAWs.
