Ring Modulated Generative Patch

YouTube via isotopeofme. via poictesme on the forum.
"Sunday morning generative patch with the VCO sine outputs ring modulating each other. Sounds a bit like I remember space mountain sounding! The lower part of the patch is one of the 2 oscillators being driven by the sample and hold, then heavily filtered to keep only the bass notes. The creschendo is the 24db VCF self oscillating thanks to a rising saw LFO on the secondary CV input."
Here's the patch:
