VCV Rack is quite fun and shows how the skeumorphic interface to things like music and synthesis is actually quite useful and understandable. While things like supercollider and pure data exist, it's hard to argue that VCV Rack's interface isn't a lot simpler to get going with. I wish popular DAWs would learn a thing or two from it tbh. Connecting VSTs with the skeumorphic interface is a better experience than someth…
There's a lot in Rack that isn't skeuomorphic. Really, a very big lot. In fact, even the patching process is only barely skeuomorphic - it doesn't obey the laws of physics in several different ways.
Reaper has no modular environment at all, so "connecting VSTs" is not really a thing in that context - the data flow is almost always linear.
