This is a really good demo/intro of the Minimoog. I've been learning synthesis on my Behringer Model D, which is my very first hardware synth, and I love it! It's such an intuitive interface to play around with. I hadn't thought of using osc 3 as vibrato yet, I'll definitely have to try that out. Your playing sounds amazing btw!
Yea analog is way better over time. You might be able to make them sound close in certain instances but over the wide spectrum of making music they are significantly different
