@prom, I agree that it's not a very polished track, and I am considering adding vocals. I'm a bit disinclined to do anything much at the moment until my hearing issue settles down. The weird thing is that although the hearing in my left ear isn't down that much ~ -20 db, I'm getting what I can only describe as Doppler shift effects, weird harmonies in my left ear vs my right. If I listen to a popular song through my left ear, it sounds vaguely familiar, but wrong. Interesting, but not useful.
Re the subharmonicon patch, the image is a screenshot of my patch, which is identical to the Omri Cohen version. I'm sure I could have figured it out, but yes, much easier to follow the video. The had part was finding and subscribing to all of the module vendors! I haven't done much with VCV Rack yet, only scraping the surface, so I have a bit to learn.
