So what's the minimum setup that I need to use just Clouds?

Have you tried the free "virtual" version of Clouds in VCV rack (a free Eurorack simulator)?
https://vcvrack.com/
The "Audible Instruments -> Texture Synth" module is an implementation of Clouds (legit, since a lot of the MI stuff is open-source).
You can then use the "VCV Bridge" virtual effect VST/AU plug-in to route the output of your DAW through your virtual Eurorack. Or, if your sound source doesn't support AU/VST use a virtual audio device like Soundflower or Loopback (on Mac - I'm sure there are PC & Linux equivalents) to route your audio via your virtual rack.
NB: remember, the first hit is always free... you'll soon succumb to that creeping feeling that using virtual modular gear doesn't quite hit the spot and craving real knobs and patch cables...
