Years ago I before I ever heard of Eurorack format, I wanted to get a complete MODCAN modular system.
Now? IMHO it's rather possible. Yes, critics will say "It's not REAL Analog!" Still, Andrew Belt's work with VCV is amazing. And the community momentum behind VCV is nothing short of astounding. Literally hundreds of Free modules already extend the platform.
Did I mention "Free"?
