I would say modular can be more simple than a lot plenty of beginner-focused all-in-one subtractive synthesizers. At its most simple, synthesis is no more that changing the pitch and amplitude over time. Not having delved into this example so unable to tell for sure; that set of features will already be covered by a single sound generation module, capable all sorts of wails, warbles and glissando- think of a theremin. Now you can go many paths onwards from there, start with a complex sound and use a filtering module to shape the sound over time (subtractive synthesis) Or modulate the original signal and move into the world of AM or FM synthesis. All by just adding another single module. I think simplicity or complexity with modular synths all lies in the hand of the user and I would certainly advise anyone to delve in.
