You're totally right. Best advice you can give
Generally I am still thinking about whether such a system is the right thing for me. But with 60euros I can't go wrong to learn such a system. Would be a good start to understand more modular. With very limited time it's a serious consideration whether to invest in this system too. There are already many other modular systems out and even one very good free basic one emulating Eurack stuff. VCV and has a clearer user interface.
Maybe my last question is... is there something special for MUX itself when MUX is running via MuLab? Or does every other DAW do the same here. Want to run it via Cubase for example. Thank you in advance.
