Hi,
Looks interesting.
You should also check out Eurorack-blocks: an open-source project to design your very own Eurorack module - it includes functionality that creates a VCV rack plugin from your dsp code - I’ve successfully used the faust integration.
EDIT: Okay, I just realized yours is for the Patch, whereas Eurorack blocks targets the patch-sm, but maybe there is some overlap and it wouldn’t be too hard to add a definition for the Patch to this project. Maybe @raf would know more.
Cheers
