VCV rack is praised by the great Andrew Huang in this video about current free music production software. Expect a download peak.
I know mr. Huang is a youtube star and so busy to find newer videos on youtube with 0.6.2 interface at least. I think he even don’t use it actually. But who cares - he bring another fame to VCV with 1.6 mln subscribers, and that’s awesome.
He says in the vid that he uses it when he can’t take his hardware rack with him. Which I assume is often.
