VCV Rack + Reaper + Keystep: Audio Settings

Hi Folks, super newb again.I made some patches that I like with VCV Rack then I open up my patch in the VST, but no matter what settings I try I can’t record the audio in the Reaper? (In Reaper I have tried every input: all midi instruments, keystep, audio, ? - Tried every Midi CV: DAW, Core Midi. DAW-Keystep?

Sorry for asking the same questions over and over.
