It is easy if you are smart, haha. But I am not smart, so I mess up every time and then I am trying to fix it. Well, that’s how people learn, I think… But I still mess up even things that I already know, like the virtual ground thing. i already had this problem. And quite recently… I think it was with a comparator in a sequencer… There was something wrong with the reference… I don’t remember. Anyway, thanks for kind words! Perseverance is indeed what keeps me going.
